The machine only has 1g RAM (wish I could stuff more into it), but I tried it anyway. No effect. > From what I've read I think there is still one option you haven't tried. > That is to remake your boot image.

There's probably some additional incantation is needed. But... AHA! I tried building an initrd image using --hostonly. This got me past mounting the root file system and through starting udev. I could see something happening after starting udev before the reset happened, so I started video recording the screen as it failed and going over that frame-by-frame. I found it was the i915 driver that's apparently killing the system. If I blacklist it, the system boots ok. After booting, a 'modprobe i915' results in a reset. I've only been able to catch the following with video (*'s represent stuff I can't make out, as it's not on the screen long enough to get a good frame): [drm[ Initialized drm 1.1.0 20060813 i915 0000:00:02.0: enabling device (0000 -> 0003) i915 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 i915 0000:00:02.0 *** 0* can't allocate resources [bogus alignment) [0x*-0*0] flags *** [***] failed to find ***** tables v****** ****** ******* ******** PCI:0000:04:00.0 ***.... pdr*[ ********* enablling support This may be something really peculiar to this box.

I'll try to get time to pull the radeon card and see if it's the combination that's messing it up or something about the i915 driver itself, but for now I'll consider the problem "worked around".
