You need to recompile your kernel with the SYSVSHM option. I had the
same problem too a while ago, even so, X still seemed to run fine. I
assume you have the kernel sources and gcc installed?
1. go to /usr/src/sys/i386/conf and make a copy of your current kernel
('GENERIC' probably), check bootup messages if your not sure.
2. have a look in the file (don't edit!) 'LINT' until you find a line
like 'option SYSVSHM'. There will probably be two more option lines
nearby looking very similar, (like 'option SYSVSEM' I think).
3. Copy these three option lines into the copy of your kernel config
file 'NEW_KERNEL' or whatever.
4. run 'config NEW_KERNEL' or whatever you called it.
5. cd ../../compile/NEW_KERNEL and do a 'make clean', 'make depend',
'make all' and finally 'make install'.
6. Reboot and keep your fingers crossed.
These instructions are from memory so there might be some errors, check
out the FAQ that came with your distribution, usually in
/usr/share/docs/FAQ I think.
