I have Slack 9.0 on my Toshiba 5100-603 laptop..
just updated the kernel to 2.4.22pre1 wich has greatly improved the ACPI handeling..
the only thing I can't get to work on that laptop is the damn firewire..
it doesn't seem to work on any kernel after 2.4.18
I might advice to test your laptop for linux compliency with a copy of knoppix
