in a simple answer : yes, you can install SuSE packages on any linux distro. but don't ask me how to do it with red hat.
SuSE uses a program called YAST (yet another setup tool) to install it's packages. it's pretty easy to use, but it only comes with SuSE. i don't know offhand how to get a package off the cd without using YAST. but, just because i'm in a good mood
, i'll email you the program once i get back to my box. (need your email address first tho)
for the kernel, try www.kernel.org.
it's the one and only official site for the linux kernel. the latest version is 2.4.6.
