Well, I wasn't sure if it had any relevance at the time of previous
message. However, after booting up with "apm=off", I've concluded
that you need to have APM support enabled in your kernel if you want
to hybernate. Without it, machine won't hybernate. It just ignores
Fn+F12.
So for your reference, here is an excerpt from my .config file:
CONFIG_APM=y
# CONFIG_APM_IGNORE_USER_SUSPEND is not set
# CONFIG_APM_DO_ENABLE is not set
# CONFIG_APM_CPU_IDLE is not set
CONFIG_APM_DISPLAY_BLANK=y
CONFIG_APM_POWER_OFF=y
# CONFIG_APM_IGNORE_MULTIPLE_SUSPEND is not set
# CONFIG_APM_IGNORE_SUSPEND_BOUNCE is not set
# CONFIG_APM_RTC_IS_GMT is not set
# CONFIG_APM_ALLOW_INTS is not set
# I think I should set CONFIG_APM_CPU_IDLE for more power saving.
Also, you need to be careful with your BIOS setting. During
my investigation, I've found that if [Advanced]->[Power]->
[RediSafe] is enabled, linux won't hybernate. You need to
disable it.

FYI, I have DOS partition set as both bootable and visible.
Without "bootable" flag, DOS/Win won't boot right.
But this seems not affect hybernation, as toggled them
around with no effect.

PS If you have RedHat handy, give it a try. RedHat usually
have APM support turned on. I used one of its derivative.
I hope you're not offended. :-)
