I am running with the acpi_video patch, and I can have the laptop in
S3 suspend for about a weekend.  (This is with the high-cap main
battery and an expansion bay battery, btw.)  APM suspend indeed breaks
something as I could never resume from it.

There was a recent patch mentioned which I am planning to try as
well.  I know I should be able to achieve better suspended battery
life, since I could go a week or two in APM suspend from Linux.

(Before I get labelled a Linux troll, I'm a recent convert to FreeBSD
on my laptop and like it a lot so far... slimmer memory footprint and
much better documented.  ACPI suspend never worked for me under Linux,
so APM there is all I have to compare with.  Battery drain under
suspend means I have to carry around a power cord again, and that's no
fun.  I'm happy to test stuff as time permits.)
