Suspend to Disk in Asus L3C

[Joel Alexandre <jcma@rnl.ist.utl.pt>]

hi,
i want to enable sleep state 4 (S4 -suspend to disk) from /proc/acpi/sleep,
but i doesn't work.

I've tried S1 and it stoped my pc, but i was unable to recover from that 
(had to force a reboot).

i'm using kernel 2.4.20 with acpi patch 20021212-2.4.20 and 
asus_l3c_acpi patch too.

How can i get Suspend to Disk to work??

Thanks
Joel
