This is what I wanted to see. We are setting the p->bus_type = AIC_TWIN
prior to our call to loadseq();

My 2842 only downloads 369 instructions, so this looks like we are getting
the twin channel sequencer support.

Justing, according the the books on these chipsets, what exact conditions
can cause the settings of SIMODE0 and 1 to get changed, and does it matter
if we set the conditions prior to enabling the bus drivers? Could the fact
that we are doing the outb(ENABLE, p->base + BCTL); after we set the SIMODE?
registers be causing the B channel settings not to take? Also, I wonder how
a completely absent cable and termination would effect how the card handles
these things. Steve, if you go ahead and put a device on the second
channel, does it work then? I think I recall you saying there currently
isn't anything on the second channel.
