SUPPOSEDLY, the new ACPI SMAP (int 15-e820) reporting gives us a clean map
of memory. SUPPOSEDLY, we can just read it & use what it says. (Right now
we only do this in late versions of 2.3.x) The reports we are getting back
from mobile users, however, suggest that it ain't necessarily so...
Second, you didn't say what version of the kernel you are running, but I
suspect it is 2.2.x. Try disabling ACPI & see what Linux detects. If
you're lucky (i.e.: the bios guys did the right thing), Linux will detect
the right amount of memory. If not, you might try one of the later 2.3.x
kernels & see how it goes. If it doesn't work, the e820 report from "head
/var/log/dmesg" might help us see what is going on.

Why can't we use something similar to check memory sizes? I have a thinkpad
770X with 192MB and 2.2.13 only reports 64MB. If I tell linux that it has
192MB then it will crash - I need to tell it 191MB (or rather, the amount
that the machine displays on boot.
One other wierd thing happens on the TP. When I suspend the box, and then
unsuspend it, the sound stops working until I unload and reload the cs4232
module. Actually I've just found out that if I lower the CD volume in
"xmix" then the sound starts to work again.
Cheers
