There may be an option in the sbios configuration settings. IIRC, some old platforms didn't always assign interrupts to vga devices.

radeon Disabling GPU acceleration (WB disabled?)
I tried 5.2, 5.3 and 5.4-rc4 on my old Fujitsu RX220 with integrated Radeon RV100. Dmesg tells that GPU acceleration is disabled. I do not know if it has been enabled in the past - no old kernels handy at the moment. From dmesg it looks like something with MTRR maybe: WB disabled. Any ideas what I could be doing wrong?
