The problem is very unlikely to be the video card.

I like the idea of systemd, but one size doesn't fit all.

PowerPC machines don't have Egret chips.
To clarify, I was referring above to the Linux code that runs only on m68k
Macs and not the Linux code that runs on PCI PowerMacs (which was always
superior). I can't comment on the Nubus PowerMac port as it never went

For Debian 3 and earlier, current kernels generate the wrong ADB keycodes.
For the LC III, my kernel build has no Egret driver so ADB keycodes are
For the IIfx, my kernel build has the IOP ADB driver and the keycodes this
kernel produces work fine with Debian 4 or later.
