--- Comment #35 from Adam Williamson <awill...@redhat.com> 2009-09-24 18:06:33 --- update from mjg: <mjg59> adamw: It looks like it implements opregion, to be honest <mjg59> adamw: In which case the workaround is correct, but the poulsbo DRM driver is deficient (...confirmatory diagnosis) <mjg59> adamw: Would actually be pretty easy - you just need to pull in the intel opregion code from the i915 drm, and change the backlight register writes <mjg59> Oh, and add support to the interrupt handler <mjg59> I've no idea how poulsbo would doorbell <mjg59> adamw: 0x7f6a3010 (the contents of PCI conf register 0xfc on your device) is ACPI non-volatile storage <mjg59> adamw: So it certainly looks like opregion. You get to keep both pieces. <mjg59> The kernel behaviour is correct, the poulsbo DRM is just shit. Sorry. So, bottom line, opregion support should be patched into the poulsbo DRM module. Which is theoretically possible, as that bit is actually open source. I don't have the skills to do it, though.
