i'm working with set top box without disk, so i'm not interesting in 
STSW. i've been able to save some logs by mounting /var/log with NFS, 
but i've handwritten the kernel panic message.

so i've tried STSW, but it first failed because i have no swap partitions

after adding a swap file, i've tried again
saving did well, but when trying to wake up my box rebooted it. nothing 
in the log.

i'm very willing to make tests but my boss he's not :/ so i have no time 
to spend on testing Suspend To Disk.

thank you
