  My system supports 56700 and 76800 and I had it patched for 115200 at
one point.  My 28Mhz PPI '040 board had some problems running at 76800,
but I suspect they ocurred when the GVP driver was accessing the disk.
I'm going to try it again with the gvp_max_dma reduced (it defaults to
64K) and see if it will run reliably at 76800.  I think at 115200 I had
quite a few problems, so I didn't bother adding that.

  When I had a 25Mhz 68030 accelerator, I had quite a few problems trying
to run at 38400 and had to drop back to 19200 to get reliable transfers. 
[The 68030 system only had 2MB of 32 bit memory and 6MB of 16 bit memory
(configured as 8MB contiguous), so I wasn't too suprised at this.]
