    drm/mgag200: Flag all G200 SE A machines as broken wrt <startadd> · 4adf0b49
    Thomas Zimmermann authored
    Several MGA G200 SE machines don't respect the value of the startadd
    register field. After more feedback on affected machines, neither PCI
    subvendor ID nor the internal ID seem to hint towards the bug. All
    affected machines have a PCI ID of 0x0522 (i.e., G200 SE A). It was
    decided to flag all G200 SE A machines as broken.
