Nice was at -10, so I changed it to run at 0; it didn't make a
difference.  Yes, direct rending was still off in 2.6.8.1.  I looked
at my /etc/modules, and found 
parport_pc
emu10k1
8139too
usb-uhci
hid
ide-scsi
ide-cd
I don't think i need the ide-scsi and ide-cd under 2.6, but I don't
think they hurt anything.

Thanks for the suggestion.
Best,
