ACPI Bad Param on Dell 5000

With a recent -current (6/18/03) I now see the infamous ACPI-0340 error
(Could not release ACPI Global Lock, AE_BAD_PARAMETER) spewing out.
This did not happen
with a kernel from 6/5/03.  I tried to apply the patch that's been
referenced here, but apparently the Inspiron 5000 DSDT is completely
different than the later ones.  (Yes, I've upgraded to the A08 bios.)
I have the disassembled dsdt, if anybody wants to look at it or
suggest fixes:  http://www.databus.com/i5000.dsl

What has not changed from previous -current kernels is getting the following
acpi error:
ACPI-0432: *** Error: Handler for [Embedded Control] returned AE_ERROR
ACPI-1287: *** Error: Method execution failed [\_SB_.BAT0._STA]
                   (Node 0xc0eb9be0), AE_ERROR

(Also on BAT1, which is not present.)
Despite this, sysctl seems to know the charge % of the battery, just not
how long it will last.

Suspend to S3 works by closing the lid (I set S3 on lid close in sysctl).
Resume is odd in that it powers up right away but the screen takes 30-60
seconds to come back.  Also, network stuff needs help on resume.  The
Cisco 340 needs to have its parameters re-set with ancontrol.  The 3C575
needs to be ejected and re-inserted.  In both cases dhclient fails to
re-apply the IP address, but it can be set by ifconfig.
Sound stops, but can be recovered by unloading and reloading snd_maestro.
Touchpad needs the flags set in hints to recover from suspend.

DRI/DRM doesn't seem to work.  No errors in
XFree86.0.log, but glxinfo shows direct as no and glxgears confirms.

xmbmon can't find the power controller, despite recognizing the PIIX.

The 3C575 causes frequent lockups under load.  No panic, the machine
just freezes.  Often it will cause shutdown to fail if not ejected first.

I can live with all of these issues, but I'll be glad to cooperate with
any attempts to fix them.

Thanks,
Barney
