Do you know of any other issues with memory and or amd64 and the 2.6.16
series?  I have run into a weird issue.

I have an AMD64 3200+ that runs at 2 GHz and runs *very* cool at about
34c.  My motherboard makes it pretty easy to overclock so I have
overclocked the 3200+ to 2.2 GHz and it has been running very stable
and still only around 39c, though a long compile job did get it to 41c.

When I was runing overclocked in 2.6.15 cat /proc/cpuinfo would show:

jim@keelie$ cat /proc/cpuinfo

                  lahf_lm ts fid vid ttp tm stc
bogomips        : 4409.17


Now with 2.6.16 it shows:
jim@keelie$ cat /proc/cpuinfo
processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 15
model           : 47
model name      : AMD Athlon(tm) 64 Processor 3200+
stepping        : 2
cpu MHz         : 2000.000
                 ^^^^^^^^^^
<snip>
bogomips        : 4409.17


The bogomips are showing the same though the kernel is not reporting
the correct MHz.

Does anyone have a clue what could be causing this?
