[Tfug] grub question

Friends at TFUG:

Anyone out there know how to test if boot options (boot parameters) are 
being passed successfully through grub?  In /boot/grub/menu.lst, I'm 
using the following in the altoptions section:

# altoptions=nmi_watchdog=1
# altoptions=mem=512MB
# altoptions=mem=nopentium

Since this is part of the "automagic" section, I assume the items with 
single pound signs are actually read by the program and not considered 
comments.  I'm also assuming ## or ### are commented items. 
As a test, I changed mem=512MB to 256MB, then tried the "free" command.  
It still saw all 512 MB of my RAM.  The other options are my efforts to 
get rid of GUI freezeups and the following info in my syslog and 
messages (which fills these files constantly whenever I'm doing anything 
with X running):

Uhhuh. NMI received for unknown reason 2d on CPU 0.   (or sometimes 
alternated with "3d")
Jun 15 14:13:31 hyde kernel: Dazed and confused, but trying to continue
Jun 15 14:13:31 hyde kernel: Do you have a strange power saving mode 
enabled?

I don't seem to be getting any verbose info from the NMI watchdog.
I have all power support in BIOS and kernel OFF.

??????????   TIA for any ideas...
