I have successfully used and tested an Ultrastor 34F (VESA) SCSI
controller on a box with 32MB.  In an email response from Julian
(sp?), he seemed to indicate that either VESA or EISA controllers had
no problems with DMA above 16MB (I don't know if he was referring to
his latest code, or the -current code though).  In fact, I had no
problems either, but I only ran it for a few days (but I did beat the
hell out of it for those few days:-).

These controllers seem to work just fine, I have used them in several
machines with no problems.  Looking around, you should be able to get
one in the low $200's, which is not all that much more expensive than
the adaptecs.
