This wastes a K of memory for everyone who's got an Adaptec controller.
Could we be a little more intelligent about this?

Modified: sys/i386/i386 machdep.c
Log:
If the basemem value supplied by the bootblocks, differs from the value
returned by the RTC, use the bootblock supplied value. Also, map the
'stolen by BIOS' memory in the same manner as the ISA-hole memory, since
it is really an extenstion of the BIOS. This is necessary for 32-bit
BIOS functions such as APM support on laptops, and the loss of memory
for non-necessary functions seems to be at most 4k.
