Anyway, modprobing pciehp gives: [ 896.752000] pciehp: HPC vendor_id 8086 device_id 27d0 ss_vid 0 ss_did 0 [ 896.752000] Evaluate _OSC Set fails.

If it can, it seems this is a Linux problem, right? Or is there some other way to tell? I also checked through the BIOS settings, and found nothing related to expresscards.
