Yes, the solution is kernel 2.1.1xx with CONFIG_MTRR=y. Everything is
then fixed. This message is just for information. It is telling you
that you have a buggy BIOS and the kernel has fixed things up for
you.

Yes, the buggy BIOS can indeed cause hangs. This is why 2.1.1xx has
the BIOS fixup code. So don't use 2.0.x. Note also that SMP is less
stable in 2.0.x than in 2.1.x, so you really shouldn't be using 2.0.x
anyway.
