This is a 66Mhz bus; apparently it makes no difference, as previously
noted here by rho@SDF.lonestar.org. Here's a quick summary of the emails
I recieved.
Kernel version is neccessary due bugs in the cpu identification of some
versions.. only 3 CPUs that don't freeze (kernel version is there to
know if a buggy cpu id is possible).
Thanks to all who answered, and maybe you want to email
tech_support@cyrix.com and ask for a workaround.
