Both good questions. I'm running 2.6.10-bk10 with the libata and libata-dev trees of that time now 
and it has made it through 2 ata timeouts and is 50% rebuilt on a 750 minute rebuild. If that 
survives I'll try and dial in some of the other kernels. 11-12 hour test times make it a bit of a 
bear to debug!
Actually, I'm not sure without the libata dev patch as that removes SMART support, and I'm not 
convinced that my smartd polling every 20 minutes does not have something to do with it. All I know 
is the older kernel seems to cope. We'll see. 320 minutes left on this rebuild. I expect it will be 
done in the morning if all goes according to plan. (With the 2.6.11 kernel it never survived past 
about 25% rebuilt)

This 2.6.10-bk10 is the kernel I have been running on my server for a while now (Almost identical 
hardware, just 1 less controller and a couple less disks)

Lucky I have a ready source of failing drives! 29 Maxtors. 1 is dying after 5000 hours and the other 
has 119 reallocated blocks after the first 8 hours.. Looking good thus far! <Bletch>.
