    SubjectRe: [PATCH 4/10] atyfb: set FBINFO_READS_FAST
    From
    Hmm. You're doing this for Matrix and now the aty driver.

    Maybe the problem is at the fbcon level? Depending on
    FBINFO_READS_FAST to decide whether you should scroll or rewrite
    sounds a bit silly: even if a device doesn't have fast reads, maybe it
    has a fast accelerated BLIT operation and scrolls quickly. Should the
    fbcon test perhaps be for FBINFO_READS_FAST _or_ the
    FBINFO_HWACCEL_COPYAREA bits?

    I dunno. I didn't actually check the ->bcopy implementations, maybe
    they don't use copyarea. So I'm just going by a general "this feels
    wrong" feeling..
