It also needs the correct preamble - that's what lphdisk (or in the case
of "people who couldn't understand the existance of anything but FAT 
partitions" that initial floppy that they probably threw out) is for.

Without a preamble that is calculated for at least the size you need, type
A0 on some blank space isn't enough.  A preamble for a bigger space will
do, at least in my tests, on machines known to use the Phoenix partitions. 
On such systems the hibernate volume also did not need to be at the 
beginning nor the end of the disk - it was perfectly happy smack in the
middle, as long as it was large enough.

(If you desperately need a preamble because lphdisk isn't doing something
you need, contact me privately.  My hubby has a 512Mb machine with decent
video memory, of the applicable type, and if that isn't big enough we're
jealous ;D )
