  I suspect /usr/src mounted from another system is your problem.

  I'm running a fairly similar setup, Acer MotherBoard w/BX chipset, 128Mb
Ram, P2/266, UDMA IDE Drive(only the one). I do have in the /etc/make.conf
CFLAGS= -O -pipe 

options enabled. make buildworld took 99 minutes, just last night. 

If I get a chance, I will try it with the noatime and async mount options
and see what I can get, but I can't believe that the difference between a
PII/233 and PII/266 can be that significant.
