I can confirm this bug on my Dell Latitude E5400, which also uses a
Intel Mobile 4 Series chipset (rev 07).
I have installed the 32-bit version of Ubuntu Maverick running kernel
2.6.35-24-generic. The laptop has a 64-bit CPU.
I ran through the pm_trace procedure and got this message:
[ 0.653986] Magic number: 0:608:321

The pci number is:
