Maybe no one else has the need but me...  I built a kernel with nearly 
all built in code, and it just got too big, so I upped the limit.

Then the frame buffer is probably grinding along just fine,  eventually 
it will probably be fixed by someone who has the interest.

Yes I have been able to boot the prep machine all with 2.6 kernels, 
since last May.  My question is do you have it working now with some 
image on the prep machine? 

It is entirely possible that the 2.6.x kernel's implentation for talking 
to QEMU is wrong, but it was not obvious to me how it subtly changed so 
as to look where to fix it with the newly merged pic logic.
