Please forgive my density - I'm still learning.

Here's my /etc/modules:

sd_mod
sr_mod
psmouse
mousedev
ide-cd
ide-disk
ide-generic
sbp2
lp
nvidia

I assume the driver for my IDE device is ide-disk??  If so it _is_
loaded before ide-generic, and yet I have slowdowns/freezes.  (I assume
the "IDE device" is the ATA drive, not the SATA drive, correct?)

The bugzilla page had a comment:
"For onboard chips the chipset driver must be loaded before
ide-generic."  lspci shows:

0000:00:1f.1 IDE interface: Intel Corp. 82801EB/ER (ICH5/ICH5R) Ultra
ATA 100 Storage Controller (rev 02)
0000:00:1f.2 IDE interface: Intel Corp. 82801EB (ICH5) Serial ATA 150
Storage Controller (rev 02)

Does this mean I need to find a module for the 82801 chipset?  If so I
don't see anything obvious
in /lib/modules/2.6.8.1-3-386/kernel/drivers/ide (if that's even where
one should look for this sort of thing).
