What works:

memtest86+ and CD boot menu

What doesn't work:

Won't boot the live image. When it switches from Plymouth to GUI, THE screen flushes to white and CD activity eventually stops.

What was done to make it work:

Tried safe mode and setting boot arguments like vga=791, no change. Live CD works in other machines.

Uninstalled Plymouth, same behavior.

Tried Radeon 7500 AGP card and it boots to GUI but only in 4-bit color mode at 800x600 resolution.

Additional notes:

This partucular 450ROG has the Radeon 9000 AGP 4x, 250/220 MHz, 64 MB DDR VRAM.
CPU is Pentium M "Banias". BIOS version 40.01.04.
