The contents of the segment registers are different. As 2.5.x
currently sits they only way to have a version of mkelfImage
that works for both 2.5.recent and 2.4.x is to explicitly test
the version number.

Yes so no BIOS's need to be rebuilt. But tools like mkelfImage need
some help. Hopefully I can get some native support into Linux and
then I can just skip the need to port mkelfImage, to newer kernels.
The feature freeze is on the 20th so I don't know if I will be able to
get anything in or not.

Getting support into the kernel proper is they only long term
maintainable way to go.
