RHEL4 on Via C3?

[Gaylon R Lovelace Jr]

Silent PC:  Via C3 866MHz on a Shuttle MV25N mobo, 512MB.
Trying to install RHEL4, from CDROM.

Boot from RHEL4-i386-WS-disc1.iso
I try  <ENTER>, linux text, linux rescue, all manner of different 
options -- same result.  It starts loading up the installer kernel 
(vmlinuz.....  initrd.img.....) and then it reboots.
Repeats ad nauseum.
Seems exactly like a Fedora Core 2 problem from last year:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=120685
A workaround was developed in that bugzilla.  Namely, a boot.iso with 
a kernel-2.6.6-1.383.i586.rpm that works on the C3.  I tried booting 
from that disk, and it gets rolling, but shortly asks to swap in the 
FC2 Install CD, and won't take RHEL4 for an answer.

So, is RHEL4 just a non-option, for the C3 cpu?  This box has been 
running RH8, 24x7 for a couple years, and that still works, but I'd 
like to upgrade it to RHEL, for the easy updating.

Any thoughts, opinions, or useful info?

Thanks!
