*hmm*

while this is true w/o ACPI enabled with ACPI enabled I do not get
a panic while booting a kernel prior to this commit (which is
equal to the patch you had sent me).

With your patch (thus also with this commit I guess) I do get the
panic with and without ACPI.

Conclusion: with this patch/commit I will no longer be able to boot
this problematic machine here.

Any more ideas ?
