The Finale of Seem

I have a couple of PCI Radeon 9250 cards that I've flashed with the reduced Mac ROM from TheMacElite wiki, and they're both having the same bizarre issue. One is a black reference board and I've done the resistor mod (forgot at first and just got garbled video out of it, better after the mod), the other isn't a reference board and seems to work without modding.
I've popped both cards into the PCI slot of an MDD with and without any other video card in the system, 10.4.11 installed. Everything seems fine at first. Apple symbol and loading wheel pop up, but when the OS loading bar appears, colors are shifted. Red looks blue, and blue becomes pink/purple. These both worked fine in Windows 7 as I checked them out there first. If I use VGA, the cards will just give me the weirdly-tinted video. If I use DVI, the cards will give me the tinted video and the video will blink off for 2-3 seconds, then come back on for a bit, then randomly go off again and repeat, and this starts right away at the initial loading screen, not after the driver is loaded. VGA is locked at 640x480 resolution, DVI is locked at the native resolution of the monitor, and in both cases no other resolutions are available. Quartz Extreme is not supported, though it should be since 10.4 stopped caring about PCI vs AGP on QE after later versions. Oddly, both cards show 256MB VRAM even though one is a 128MB card and one is 256MB. Clocks look correct.
If it was just one then I'd think I had a bum card, but two? That's more than a bit weird. Maybe the ROM on TME is bad? Has anyone seen anything like this?
And oh, my kingdom for either someone being able to update TME or someone to make a big ol' wiki to cover new info/files/roms/etc on video card flashing along with the other madlad antics that folks get up to with old Macs. So much information is scattered all over the place...
