Unfortunatly, that' not my experience either.
Both RedHat and SuSE heavily modify the kernel. So anything that needs
anything near kernel space (two examples: the HP management/monitoring
tools and the EMC/Legato Networker backup software) simply does not work
on Linux (linux being the kernel from kernel.org) They only work on
RedHat/SuSE. To the point of not compiling/starting/working, not just
the support part.

(One could argue that they shouldn't claim linux support then, but
specifically RH/SuSE, but I don't expect them to do that..)

BTW, it used to work much better with 2.4, but since there is no real
"stable series" kernel in 2.6, it's just a lost cause there it seems.
