Really? weird... I used to boot with acpi=off on my desktop box (don't have a 
laptop) with JAD or 10.2/JAD kernel, I didn't ever see such a behaviour. 10.3 
with jengelh's RT works very well for me, with acpi, last time I tried that one 
with acpi=off it froze my box during boot, so I'd rather prefer to avoid trying 
again... sorry, I know this isn't particularly helpful. If you really want me 
to test it, contact me via PM or jacklab forum and I'll do it.
