Grub.conf and maximum memory

Hi,

I currently have 128MB in my Linux machine, and I just got another 256MB
stick. I ran a memory test on the new stick, and it appears to have
problems above 128MB (it's low-density, and the PC recognizes the full
256MB with just this new stick, so I know it's the correct memory type).

While I'm waiting to get a replacement, I was wondering if I could tell
Linux to only use 256MB (128MB from old stick + 128MB from new stick)?

I've done some searching, and it seems like I can do this by adding
"mem=256" to the "kernel" line in /boot/grub/grub.conf.

What I'm wondering is: If I do that, and if it causes a problem and
prevents the machine from booting, how can I boot into Linux to re-edit
grub.conf to get rid of the 'mem=256'?

Thanks,
Jim
