patch to make 2.4.32 work on i486 again
- From: Jacek Lipkowski <sq5bpf@xxxxxxxxxxxxxxxxx>

Booting the 2.4.32 kernel compiled for a i486 on an i486 box fails,
because "Kernel compiled for Pentium+, requires TSC feature!" (printed
from check_config() include/asm-i386/bugs.h). To reproduce, select 486 in
the kernel configuration and grep CONFIG_X86_TSC .config
Seems strange that no one noticed this, am i the only one still using 486
boxes? :)
