That seems like an implicit bit of advice :), so I've just joined the
list. Thanks!

Good summary, one I didn't have quite enough knowledge to assemble.

I've pulled down the latest CVS snap, compiled everything, and tried the
above in several combinations, along with varying the LILO command line:
vga=0 noacpi init=/bin/bash
vga=0 acpi=off init=/bin/bash
The 'acpi' options don't seem to have much effect; leaving 'vga' at the
value set in my '/etc/lilo.conf' (0x317) turns those {1}s into {3}s
(i.e., instead of waking all but the video, the only thing that comes on
is the WiFi light, and there's no response to any keystrokes.)
In short, no change.

Yes and yes. The result is {3}.

Will do - thanks!
