I realise that machines supporting S4BIOS are becoming rarities (a bit like real modems vs 'winmodems' I guess) but has anyone heard of anyone succeeding - or failing - to hibernate with machines that used to work? I'm pretty sure I'd have noticed posts/PRs re this, in acpi@ at least. The 1500c is still in service, still using APM, so I can't pull it down to test either this or its big issue with ACPI back then (not switching to battery power on loss of AC - clunk!) Maybe when I get a Soekris or similar box going, paqi can be put out to pasture for its 12th birthday, like an old working horse :) cheers, Ian
