I tried the upgrade and ran into the same problem as everyone else.  I'm
using a slightly customized kernel, but the cpu stuff is exactly the
same as GENERIC.

When I boot my old kernel, the CPU information is reported like this:

Timecounter "i8254"  frequency 1193182 Hz
Timecounter "TSC"  frequency 1608231018 Hz
CPU: AMD Athlon(tm) XP 1900+ (1608.23-MHz 686-class CPU)
  Origin = "AuthenticAMD"  Id = 0x662  Stepping = 2
  AMD Features=0xc0480000<MP,AMIE,DSP,3DNow!>
real memory  = 1073676288 (1023 MB)
avail memory = 1035325440 (987 MB)
Pentium Pro MTRR support enabled

When compiled with the new gcc, I get:

Timecounter "i8254"  frequency 1193182 Hz
CPU: AMD Unknown (286-class CPU)
  Origin = "AuthenticAMD"  Stepping = 0
panic: CPU class not configured

It looks like TSC is also not detected.
