[CentOS] Kernel panic from install CD

I have a bunch of DecTOPs.  Use the AMD Geode chip.

Yesterday I upgraded one of them, and got the dreaded Kernel panic. 
Something about powernowk8.  I could boot up with the old kernel, though.

I know I have to put in a bug report on this, will do shortly, but first 
wanted to try a fresh install on another DecTOP.  At the prompt, I 
specified:  linux askmethod

After it loaded the kernel, it died with the same Kernel panic.  This is 
bad.  Very bad.  If they fix the kernel (when, please?), I will need to 
make a new install CD (how?).  Yes, I can put the drive in another 
system, do the install, move the drive, then run system-config-display, 
but I was hoping that 5.2 fixed the install problems i was having on 
these DecTOPs with 5.1....
