Justin,
I was looking at the code for aic79xx, and it appears that the channel is
hard-coded to 'A' in a number of places, rather than using SCB_GET_CHANNEL()
(e.g.: calls to ahd_reset_channel in aic79xx_core.c). Was this
intentional? Is there only one channel per aic79xx host?

Updated aic7xxx and aic79xx drivers for 2.4 and 2.5 can be found here:
http://people.FreeBSD.org/~gibbs/linux/tarballs
Notable changes:
o Both drivers support Domain Validation
o Memory mapped I/O is now a config option
o New memory mapped I/O register test that will hopefully
weed out broken VIA chipsets
o The reboot notifier hook has been disabled. The driver wants
to shut itself down prior to reboot, but the reboot notifier is
now called too early in 2.5.X for this to be effective. It looks
like it might be possible for the driver to grow a device shutdown
routine, but it was not obvious with a quick look at this new feature
how to ensure that the [sd, sr, etc.] driver's shutdown routines
would be called prior to the aic7xxx driver's routine. Some guidance
in this area would be appreciated.
o Tag depth changes are now communicated to the midlayer.

Yes. There is only one channel. Much of the code was ported from
the aic7xxx driver which, due to the aic7770's twin/narrow capability,
must have a concept of "channel". At some point, the channel references
may be completely removed from the code, but they are harmless.
