[ltp] R40 hibernation?

[Kevin Mescher]

I've got a new R40 (Model 2897), but I'm unable to get 
hibernation to work.  Here's what I've done so far:

Converted the NTFS partition (stupid XP) to Fat32.

Created a save2dsk.bin file on the Fat32 partition, enough 
to hold system+video RAM.

Checked it with the phdisk floppy (from IBM's website).  The 
program says I have a save2dsk.bin on the C: drive (where 
it should be).

When I hit Fn-F12, all I get is a beep from the system.  
Same when using 'tpctl --H'

When I use 'tpctl --H', I get this:

tpctl: SMAPI BIOS error 0x91 ("system is invalid") -- 
exiting.

Suspend to RAM works fine.  Any idea on what I'm missing?
