Note that the 2.0 Cyrix patch is a semi-official offshoot of
the real patch which is development work against 2.1. The current
version is known broken with VSPM enabled with non-power-of-2
sizes of RAM (a missing pg_dir++) and may enable some less than
stable functionality on the 5x86.

(The next 2.1 version will fix things, describe Cx486 family
chips in /proc/cpuinfo correctly, recognise Cyrix M2 (if you
can find one) and use AMD's extended CPUID to get the hardcoded
CPU description on K5 and K6's. I doubt I'll find time to do
a 2.0 version but someone else might)
