just for the record, in my case, 'swsusp' (normal, not the 'swsusp2' by
Nigel Cunningham) works *perfectly* without DRI and AGP. 'Perfectly'
means that I can suspend from X (obviously, unaccelerated) and
successfully resume on X with the USB and ALSA (0.9.7) modules loaded
(but as I don't have any USB devices here, I can't tell if USB working
let you suspend/resume). This is a starting point, I hope, even for the
'swsusp' mode.

I never tried 'swsusp2', I could give it a try if necessary. The same
for 'pmdisk'.

Well, I could try on 2.4.23 to find out if the problem is 2.6 or not.
Anyway, what is strange is that the problem is on an Intel graphics
chipset, so it the 'intel-agp' has some resume code, it /should/ work.
And this isn't the case :-(

Thx, bye,
