ACPI BIOS problem

Since there is no linux-notebook, I'm going to try posting to here with
a problem with the Inspiron e1505/6400 series. I'm running with the
latest A12 BIOS, which still has the problem.
I am trying to use the Expresscard slot ( http://www.expresscard.org )
on the PCI-Express bus with an eSata card. If I have the card plugged in
when the system boots, no problems, everything is hunky dory. If I try
to hotplug the card after the system has already been up and running
(yes, I have verified the hardware supports this, both the chipset and
card) I am unable to. I have tried the pciehp (pci-express hotplug)
drivers, which don't work because Dell has not implemented the _OSC ACPI
function. I have verified this with the Intel engineer which maintains
the driver. I have also tried the acpiphp driver, which doesn't work
either. Anyone, hopefully a Dell engineer reading this, able to tell me
how I am supposed to get hotplug working on pci-express?
Oh, and just to let you all know, it works under XP because XP uses a
different way, although Vista does use the correct _OSC function call as
I found in my research on the net.
