HP D325 Panic Fault Trap

I have a new HP D325 minitower with an Athlon XP 3000+ processor, 512 
RAM, 40GB 7200 HD, CD-RW/DVD-Rom.

If I try to boot a 5.2.1 based CD (Official Install or FreeSBIE) I get 
this message:

If I use the 5.3 floppy I get get into the sysinstall by disabling ACPI.
Once I have it installed and it tries to boot off the HD I get the same 
as above.
If I do not disable ACPI when booting from the floppies the kernel 
starts and I get this:

CPU: AMD Athlon XP 3000+ (remaining spec omitted)

Panic: page fault
Uptime: 1s

At that point it is totally frozen, no Ctrl+Alt+Del, no scrolling up or 
down, no nothing.

Any ideas, hints, patches, bios settings; anything??
