Ya, I didn't suspect it was going to do any good when I did it, but hey, it 
was something that didn't take more than 5 minutes to do on a 3/50, and the 
error message didn't exactly specify what part of the kernel it thought was 
too big ;-) :->

As a followup:  I simply commented out the appropriate sunmon_abort() line
in pmap.c, and let things continue... The machine has been up for about 16 
hours now, and is happily re-building the world...  My guess is that the 
condition ( avail_end > hole_start ) is incorrect, as avail_end is around 
0x7fc000 on my machine, and hole_start is at 0x100000.

Later...
