FWIW, Red Hat 7.x worked fine with my CD burner, but I was not able to get my
new DVD burner to work until I went to Fedora 2. I suspect if you back port
the DVD writing tools like growfs, it might work, but possibly won't.

IIRC, most rpms on Red Hat are built, optimizing for a Pentium-II class
computer, but only using the instructions available in all x86 machines. The
kernel, glibc, and openssl have machine specific rpms.

If you build recent GCCs from scratch (ie, not using rpm), it will configure
the compiler so that by default it restricts itself to the common instruction
set, but optimizes your program for the particular machine it was configured
on.
