#8457: Blank screen after boot on Radeon Mobility 4670 HD

I'm running Haiku A3 on MSI EX625 laptop, which has Radeon Mobility 4670
HD on board. The PCIID for this card was added to radeon_hd driver listing
very recently. I've built radeon_hd driver and the accelerator as of
"hrev43937", and put them in places of the original files:[[BR]]
''/system/add-ons/kernel/drivers/bin/radeon_hd[[BR]]
/system/add-ons/accelerants/radeon_hd.accelerant''
With new radeon_hd I'm getting a bright garbage-looking screen on boot
(screenshot to be attached). I can boot fine with fail-safe video mode
(which forces VESA and disables radeon_hd).
It might be relevant that "connector_read_mode_lvds" sees my native
resolution as 1400x900, where the actual screen resolution is 1366x768.
However, I get the same white garbage if I try to boot with a forced
1024x768 resolution (via the boot option), which works fine with VESA
driver.
