The intel driver on Fedora 14 seems to handle it correctly, which
would suggest it's a nouveau bug rather than an xserver bug.

Out of interest, how accurate is the colorspace information you get
from the EDID normally? I know you do an auto-profile in oyranos and I
wondered if typical monitors were accurate, or the EDIDs just get
stuffed with some half-correct (semi-random) values by the vendors.

Obviously DreamColor monitors are pretty accurate, but what about the
bargain basement LCD panels and the non-name LCD screens used in
typical notebooks?

Thanks,
