THIS IS PRE-PRE-RELEASE SOFTWARE - USE AT YOUR OWN RISK!

I think this should fix the problems with devices that want asynchronous
transfers.  So hopefully all the tape drives and removable media that
people have will work now..

### ONCE THIS IS APPLIED, YOU _MUST_ REASSEMBLE THE SEQUENCER CODE ###
### INTO aha274x_seq.h BEFORE REBUILDING THE KERNEL, OR THIS PATCH ###
### WILL NOT WORK!                                                 ###
