O.k., but you shouldn't do any ofthis testing as root.

I can't see any IRQ 4 here. What does Marc say?

*What* does? What non prerelease kernels?

Nonsense. It's the latest. APM is dead and forgotten. I can't boast your
academic qualifications, but I know how to go to web sites and enquire
about my hardware, then follow up the leads. Your modem, at least,
doesn't support it (lspci -v).

Just patch your *kernel.org 2.4.18* kernel ACPI drivers with the latest
ACPI patches. But, as I said, I don't know whether your Dell supports
it.

Just you get your modem working, first.

It might just.
