Ok, off the top of my head:

Storage drivers that are known to work with amd64 and 4GB of RAM or more:

aac
amr
iir (6.1 and above only)
ips
ahc
ahd
ciss
arcmsr
mpt
isp

Storage drivers that should work, but might need more testing and 
validation:

twa
twe
mlx
mly
amd
trm


Storage drivers that are known to have problems under load:

ata
hptmv


Storage drivers that simply will not work::

asr
asr
asr
asr
asr
pst
ida
sym


This list isn't definitive, and I've purposely excluded ISA controllers
and controllers that are significantly out of date, but it's close
enough to give you a good idea of what to shop for.

Personally, I feel a bit bad that ata and sym aren't in the first group,
but there are only so many hours in the day.  Both present interesting
challenges.
