You can try doing the following:
edit grub.conf and append this to the second line "mem=2048M"
Of course don't put the quotes in there. I believe this can still
be passed to the kernel in such a manner. I'm not sure if you can
pass mem=2G of course I suppose you could try it.
If you don't want to make any permanent changes until you know it
works, simply reboot and at the grub screen hit a key so you can
edit. The spacebar should suffice or 'e'. Arrow down to the
second line and hit 'e' again and place the above mem statment at
the end.
