2.4 fixes in git

Contrary to earlier announcements I commited a few Linux 2.4 fixes into git. The fixes are:

o Crash fixes for kernels built with gcc 3.4.
This does not fix all issues with gcc 3.4. Some configuration might fail to link and there might be other, yet unknown problems so using an older compiler stays the safe bet.
o Fix ordering of serial interfaces for Malta. This makes sure the onboard serial really will be the console.
o Support for a few CPU cards for Atlas and Malta that are supported in Linux 2.6. Probably few people care but it's a big item for me, my usual Malta configuration didn't run 2.4 ...
