addendum: ubuntu 7.10 here if it makes a difference and how can i tell if
i'm running 32 or 64 bit linux ? ( there will be a lot more "newbie" type
questions i'm sure )
Any help will be appreciated.

I think if you select the AMD64 Ubuntu, you get 64 bit but if you are running BOINC right now, you must be running 32 bit. If you have 64 bit, it usually takes getting ia 32 libraries to get BOINC to work the way I do it. It has become one of my steps when I install Ubuntu.
the version 527 error may be from not being metioned in the app info xml. I just looked at my app info's and they only refer to 515, so maybe I am missing out on some types of work units.
So help us out fellas, what does a good app info xml say nowadays? Do we have a 5.27 Seti Linux app? I see one of Crunch3r's for 32 bit Linux refers to 5.28.

I don't run Linux and although I try to follow the discussions on the subject the details often get lost. But I do know there are versions of BOINC for both 32 bit and 64 bit, see the all versions page. Through 5.10.21 they were trying to make builds which would install on any version of Linux, more recently they changed to builds for Ubuntu though I think the target is the version before 7.10.
The S@H applications situation is more complex. The stock build for 32 bit Linux/x86 is version 5.27, but for 64 bit there are both 5.12 and 5.28 versions. IIRC it depends on the platform string BOINC sends which of those would be downloaded.
But with an app_info.xml the S@H application version doesn't really matter, there was a problem before BOINC 5.5.13 but all recent BOINC versions are OK. But again the platform string reported by BOINC does matter, the servers won't send work unless that matches one of the platform strings they expect.
AFAIK, the app_info.xml files Crunch3r supplies with the Linux builds should work well, I don't recall any complaints.

OK, now another question on my newly linuxed laptop the benchmarks are
Operating System Linux
2.6.22-14-generic
Memory 1010.05 MB
Cache 1024 KB
Measured floating point speed 612.46 million ops/sec
Measured integer speed 1190.09 million ops/sec
while the results for the same compter 2 days ago were ( before linux )
Operating System Microsoft Windows XP
Professional Edition, Service Pack 2, (05.01.2600.00)
Memory 1022.17 MB
Cache 976.56 KB
Measured floating point speed 1785.81 million ops/sec
Measured integer speed 3256.43 million ops/sec
Any thoughts on this ?

Hmm, your result under Linux shows:

That seems to indicate the CPU is being throttled under Linux by Cool'nQuiet or whatever the Linux equivalent is. Beyond that, BOINC on Linux is built with a different compiler than BOINC on Windows, so the benchmarks do tend to be different. Earlier this year the developers worked on equalizing them by using specific optimization options for that part of the Linux build, but I don't think they used a Turion system to do the comparisons.
When you get a chance, switch to a 2.4 or 2.4V build. They're a touch faster and use the current multiplier when reporting fpops_cumulative, so your credit claims would match current standards.
