[SOLVED] Tablet PC - Wacom not detected by HAL

I have a Motion M1400 tablet pc. I've had ubuntu on it for a few years with no problems but I want to switch to arch (its so much better!). However, the wacom input is not being detected. I've gone through the forums here and on ubuntuforums trying various solutions - Neither linuxwacom, linuxwacom-dev or linuxwacom-cvs seem to do the trick.

But I think the more fundamental problem is that HAL is not detecting the wacom device at all  (according to lshal)
This is really puzzling me - it 'just worked' under ubuntu - and hal detection seems to work for other tablet users under arch as well

Can anyone help me with this? Is it worth trying to replicate the hal( or udev?) settings that i had in ubuntu in arch?
HAL doesnt seem to output any log files that I can use to debug.
and if it helps the relevant error is Xorg.0.log is

usbDetect: can not ioctl version
Wacom xf86WcmWrite ISDV4_STOP error : Input/output error

but I assume this is a result of no hal detection
thanks!

FIXED!

turns out this was an acpi error (never underestimate the value of going through log files slowly!)
i had used:

acpi=off

as a boot parameter because arch wouldnt boot otherwise
removing this line and instead using:

pci=noacpi

does the trick!

hope this helps other m1400 tablet pc users!
