I also noted a number of "unaligned trap" warnings appearing in the kernel log due to the Xorg process. I don't recall seeing them prior to this date, but will need to investigate further to verify whether they are due to the latest radeonhd plus audio. The unaligned traps, on Alpha, are not a show stopper, it just means the kernel emulated a misaligned memory access the CPU couldn't perform. The main detriment is a large performance hit. But I understand that on the Sparc platform misaligned accesses result in shutting down the process that generated them so ultimately, one should avoid them, if you want generally portable code. I will investigate further to verify whether the radeonhd driver is causing them, or whether it is something else in Xorg. The patch should not introduce any misaligned memory access, if i remember correctly gcc should (depending on compiler options) take care of this. I'm working with different operating systems and cpu architectures including solaris and sparc all day, and know the underlying problem. My best bet would be the x86 emulation, since i don't really know how this is implemented on sparc.
Thanks for the clarification of DVI versus HDMI. If you want some more infos about this take a look the HDMI Standard (http://www.hdmi.org/download/HDMISpecification13a.pdf), unlike most of the vesa standards this one is available for free.
Running rhd_dump is rather boring. It returns zeros only. I presume that is not expected. Output follows Oh, oh that's really, really bad. I can reproduce the problem if i put my RV630 in a motherboard with onboard 780G. If the RV630 isn't selected as primary video device in the BIOS it doesn't get initialized at POST, resulting in all kind of weired behavior (including wrong colors, all zeros in the 7300-73ff range, or even no picture at all).
That's something i really can't do anything about without some good atomBIOS documentation, but since this bug will affect most of the people trying to get more than one card into a motherboard it should get a little bit priority.
