You can try the aic-driver which is available at

	ftp://ftp.dialnet.net/pub/linux/aic7xxx/

I made some good experience, this driver seems to be more stable than
the one included in 2.0.33 (which I currently use), especially when
activating special features such as SCB paging and tagged command
queueing.

BTW: the aic7xxx driver changed alot in the last kernel releases, you
might also give 2.0.34 or 2.0.35 a try.
