Been using 2.5.x all this time. Just did the following mod on 2.5.72-bk3:
#ifdef CONFIG_SOFTWARE_SUSPEND
if (state == 4) {
if (state_string[1] == 'b') {
do_suspend_lowlevel_s4bios(0);
} else {
software_suspend();
}
goto Done;
}
#endif
And it activated bios suspend just fine. It didn't resume properly though.
The bios resume screen was left behind and the whole setup hung. I've
been using the suspend2disk functionality of this laptop under apm and 2.4.x
just fine (for months really - I rarely 'rebooted' my laptop) so I don't
think it's the bios that's b0rked.

"The Iraqis are sick people and we are the chemotherapy," said Corporal Ryan Dupre. "I am starting to hate this country. Wait till I get hold of a friggin' Iraqi. No, I won't get hold of one.
