I've updated to linux 2.6.7 and applied the acpi patch for it. The
behaviour is now a bit different.
When trying to suspend (echo 3 > /proc/acpi/sleep) I now get the following:

PM: Preparing system for suspend
Stopping tasks:

Device 0000:00:1d.7 is the USB 2 controller. If I remove the ECHI module
the behaviour is as previously (i.e. locks up).
I don't know if this is a new bug in the EHCI module or if this is the
source of all the problems on this machine. I do not know enough of how
things work at that level to determine if the USB controller could
prevent the standby.
The BIOS doesn't have an option to turn of USB so I can't try it with
the hardware disabled.
Any ideas?

Oh, how nice, it looks like progress with the drivers when it dies wo one ;)

Seriously, please try again with init=/bin/bash and then add drivers
in multiuser mode until you find the culprit.

Also ACPI modules may have to be removed.
