Just remember when making changes like this that the old code works fine
for some people. I've had 4M in my 7600 for a long time, and never once
had a problem with Linux saying I only had 2M. I don't often have the
time to do kernel hacking, but I'll try to get a kernel with this patch
up and running on my computer to see if it breaks things. I suspect it
will, since it seems that the old way of detecting is removed.
Hopefully I can get back to you on this in a few days.
