Rodney W. Grimes b145f751d3 This is a fix for the 32K DMA buffer region that was not accounted for,
it relocates it to be after the BIOS memory hole instead of right below
the 640K limit.
THANK YOU CHRIS!!!

basically, reserve a new 32k space right after firstaddr,
and put the buffer space there...

the diffs are below, and are in ~cgd/sys/i386/i386 (in machdep.c)
on freefall.  i obviously can't test them, so if some of you would
look the diffs over and try them out...
