I've downloaded the precompiled kernels, but won't get a chance to try them till the end of the weekend, at the earliest.

Remember that newer kernels usually have some new configurable options so an old config won't apply cleanly. In the transition from 2.6.28 to 2.6.30 these comes to mind:
--- Code: ---Processor type and features --->
[*] Supported processor vendors --->
[*] Support Intel processors
[ ] Support Cyrix processors
[ ] Support AMD processors
[ ] Support Centaur processors
[ ] Support Transmeta processors
[ ] Support UMC processors
--- End code ---
Really bad things seems to be possible if you don't enable this option and configure it correctly for your cpu. I can't say that this option is the cause of your problem (there are several new ones) but I always check every new option during kernel upgrades and computation times are the same for me regardless of kernel version.

Yes.

As noted by people over at S@H forums, the GPU seems to claim credit that is about 30% higher than what the CPU does. If your wingman use the CPU you will be granted the lower value but if your wingman use GPU like you, you will receive the higher value it seems.

The cuda app usually overclaims (other times underclaims) because it can't calculate precisely the flops needed for a certain workunit.

Shameless plug:
I've managed to climb to the #3 spot in the Top hosts list. This is probably the highest I'll ever be so I'll savour the moment. :D
PDF attached for future proof.

congrats! when i get my 2nd 285 to replace this tesla maybe ill be able to reach around 15k.
do you process ap too or just mb? i blocked ap and am only doing mb.
either i'm doing something wrong to only break into the 10ks and now dropped to 9.9 since the weekend or something.. i see so many people with considerably higher rac with basically the same equipment.. unless its because i keep this machine so busy being a workstation... my load averages are consistantly betw 5.0 and 8.5
