I don't suggest complex solutions in FAQ's.  If people want to do
complex things on their end, they are welcome to do it.

I thought 4.1 would automatically size SYSPTSIZE based on the shared memory
configured.  At least that is what BSDI support said.  They said the
SYSPTSIZE change would not be neeeed in 4.1.  If you don't make the
SYSPTSIZE too, does the kernel still boot with larger shared memory
segments?
