My only complaint being that it doesn't seem to like ECC DDR modules (which a i845 _should_ support as far as I know), but maybe the ones I had lying around were bad. >Do I need APIC to get the hyperthreading work?

One comment: if you're going to use the built-in graphics (which work fine - even 3D is quite respectable for "everyday" usage), I'd get DDR-333 memory, since the UMA memory model means that especially at higher resolutions you _will_ be losing part of the memory bandwidth to the graphics.
