The reason the driver fails is because it had problems with highmem
buffers. Staying below this was the safe solution. But losing more then
half of your ram if you have 2GB is not acceptable is it?

! They have a _lot_ of patches in there but their kernels tend to be
fairly stable, have had a lot of testing, have support for most hardware
out there of which a driver is available but is not included in the mainline
tree yet (or never will).
This was just bad luck I guess.
The 2.4.14 XFS rpm is actually just a linus tree with XFS. So if you
would checkout a CVS XFS tree you would get all the latest fixes
and a 2.4.17 kernel whithout losing any features that are available in the
2.4.14 release. This kernel is not tested as much as an official
release but does a have relative wide userbase of people testing it for
problems.
If you really need a fix that came with a later kernel this would be your
best shot. Bit if your box is doing just fine there is no real hurry. The
most important production database server at work is running the 2.4.9
1.0.2 release since the redhat kernel has drivers for the gigabit ethernet
card included.
Note that the 2.4.17 kernel has gotten a lot of decent reports and Marcelo
is doing a lot of good work.
