 What does "vmstat -s | grep colors" show on this machine?  If it's a
 reasonably recent Intel CPU with 6MB or 12MB of L2 cache, this will
 probably not be a power of two and would explain what you're seeing.
 
 In -current this was fixed by both fixing the cache detection stuff
 and rev 1.32 of sys/arch/x86/x86/cpu.c.
 
 Cheers,
 Simon.
