Yes, fn-F7 works on the console, it's only disabled in X.

I have the latest available BIOS for the A20p (IVET69WW, dated 20 Jul
2004). As for your other question, I am a newbie so I'm not sure I'm
doing the right thing, but running the command "acpi" in a terminal
yields:

 x@y:~$ acpi
 No ACPI support in kernel, or incorrect acpi_path ("/proc/acpi").

So I guess ACPI is not built into the kernel (Ubuntu 6.06 Dapper
standard install, kernel 2.6.15-26-386)? Is there an easy way to fix
this, perhaps via apt-get?

Thanks,
Hans
