I have 4GB RAM installed and BIOS recognize 4GB RAM.
Linux kernel (Ubuntu-7.04, 32bit-PAE and 64bit, openSUSE-10.2
32bit-PAE and 64bit) tells me: only 3GB of RAM are installed.
Any other user with a 4GB Thinkpad? tytso?
What can i do? Please help!

Please post your bootup dmesg output. If your chipset doesn't support
memory remapping above 4GB or the BIOS doesn't enable it, you won't
be able to use all 4GB of memory.
Here is me dmesg output, fist 400 lines.
BIOS-provided physical RAM map:
BIOS-e820: 0000000000000000 - 000000000009f000 (usable)

Yes, that's the problem. Your BIOS/chipset only provides about 3070MB of
usable RAM to the OS. Unless there is a memory remap option in the BIOS
that you can enable, there's not much you can do about it.
