I am pretty sure that suspend-to-disk (S4BIOS) is supported, however, in order 
to use S4BIOS, the BIOS needs to have a place to suspend to.  This is usually 
achieved with a little utility ( http://www.thinkwiki.org/wiki/Tphdisk ) that 
writes a FAT32 Partition or similar.  If you have that partition, 
suspend-to-disk should work just fine.  Good luck,

Eric
