Following your replies I've done the following, in an attempt to isolate the problem:
(memory #1 - "old" memory, memory #2 - new memory)

- Runned memtest on both memories with 0 errors
- Booted with both memories... kernel hang
- Booted with memory #1 on slot #1 successfully
- Booted with memory #1 on slot #2 successfully
- Booted with memory #2 on slot #1 successfully
- Booted with memory #2 on slot #2 successfully
- Booted with both memories on windows successfully

For some reason, my kernel hangs if I have 2 GB of RAM installed.
And I do have High memory support (4GB), although that doesn't seem relevant.
Ideas? :X

Thank you all for the quick replies.
Cheers

An alternative to running memtest (which is quite easy to do, I might
add) would be to remove the original RAM and see if the computer boots
with the new RAM only.

Alternatively, you could just run memtest, as it is included with many
BIOSs now. It doesn't take long to identify problems, if there are any.
I find that test #5 is the best test for finding problems, however it
tends to keep you in the dark until it's finished the test.
