I've tested it on my PowerBook5,4. The summary is: it almost works perfectly. > Please test and let me know how it goes, as I don't have any macs and > we may need additional quirks or finer grained model info.

I've compiled the driver this weekend and and it detects the attached dvi-monitor (I do have to boot with the monitor attached to enable this, after that it keeps working (specifically it works after a suspend)). Unfortunately I still have to flip a few bits in FP_GEN_CNTL to actually enable the output. The bit-twiggling I use is described at: http://ozlabs.org/~jk/docs/mergefb/. As a result the display won't blank when my normal screen does. Aside from these very nice result I've noticed two things not working quite allright: 1) I've experienced a couple of crashes, I've not been able to determine the cause. However, X has been running for more than a day now without any probles. I will get back on this one when I find a cause. 2) Once after enabling the external display it seemed as if some parts of the big screen were mapped onto other parts. As if some portions of the memory where duplicated. I will see if I can take a screenshot next time. I'm very sorry I can't give a better report on the problems but I hope it's useful none the less.
