did you remember to emerge --sync, maybe even emerge --metadata ?
frankly, I am not sure what the last one does, but I believe it could
update data concerning the ebuilds themselves, which could be a
potential source of problems.

there are 2 ways I know of:
1) simply reboot on a gentoo boot cd and type 'memtest' or some such
	at the boot: line.  (Refer to the on-disc documentation for help
	concerning what exactly to type)
2) a)emerge memtest86+; 
   b) find memtest.bin and move it to /boot/memtest86plus 
   c)add a grub line that looks like this:
	title=Memtest86Plus
	root (hd0,1) # this refers to my boot partition.  you may have
		     # to change this setting.  
	kernel /boot/memtest86plus/memtest.bin
   d) reboot and use memtest from the hard drive.

If, when you emerge memtest86+, you have /boot mounted, the emerge will
plop the .bin file down right where it needs to be.  If not, the output
from the emerge should giveyou the info you need.  

Of course, memtest.bin doesn't have to be on your boot partition, if
grub can read the root partition.  In fact, you might not even have
a /boot partition.  Just make sure the root line for memtest in grub is
proper.

You could try a CPU stress test.  If the cpu isn't working properly,
using it at 100% capacity for a little while ought to make that
apparent.  But your results may vary.  A rudimentary query on google
points me in the direction of:

However, i don't know if it's source and if not, there's always a valid
security concern when running others' binaries.  something to keep in
mind...
