[9fans] 9load freezes

[Jamie Gavahan]

Hello all,

I have a Dell Inspiron 1000 laptop with the latest BIOS upgrade (A08).
I recently learned of plan9 and was really impressed; I decided to try
and get rid of Windows XP and OpenBSD.
The laptop boots the install CD, but this is the last thing I see

"PBS1...Plan9 from Bell Labs
 ELCR: 06b8"

It freezes right before loading the kernel. I believe this is because of Dell's
poor ACPI implementation; I have heard rumors of a buggy DSDT.  Does
anyone have any workarounds or fixes so that I can dive into Plan9?

Thanks,

Here are what I believe the relevant parts of a linux dmesg are
