SEMVMX apparently too low after domu kernel update

After updating a domu kernel just recently (from .5 to .7), outside of 
all the other issues I've had that you may be aware of :) ... postgresql 
is failing to start giving the message:

FATAL:  semctl(65536, 16, SETVAL, 536) failed: Result too large or too small
HINT:  You possibly need to raise your kernel's SEMVMX value to be at 
least 536.  Look into the PostgreSQL documentation for details.

Although I don't believe I should have to alter any of these values to 
get it to function, I've tried to accommodate postgresql but no change 
seems to allow it to function. Raising one limit produces another error, 
raising that limit produces the original error ... rinse/repeat.

Is this one of those recompile scenarios or has something actually been 
lowered and is preventing pgsql from starting?

Thanks for any info,

Sarton
