Hi Frans,

Thank you very much indeed for your answer!

I also tried to install gentoo offline (with a portage snapshot and manually 
downloaded distfiles). The snapshot was form the 14th August 2009. At this 
time the source packet "gentoo-sources-2.6.30-r4" was the current stable for 
the x86 platform, which I used.

Maybe the output in some cases may variey, but at all I had the same problem: 
dmesg only shows that a card was inserted or ejected and also lspci doesn't 
listed the card (without the -H1 parameter).

After that i first tried some other *nixes, but with moderatly success.
But 'cause Linux is my favorite os, I thought, I try it with posting here on 
the mailing list.

I read this page also before, but it doesn't help. eg. pcmcia-socket-startup
doesn't help and the bridge problem with the subordinate doesn't fit, but I 
already have tried the "pci=assign-busses" commandline already, unfortunately 
without success.

That's an idea, but in the installed gentoo system there where no hwsetup 
utility (only the usual init scrips, which simply loaded the necessary 
modules). I admit, that I don't know what exacly hwsetup does, but it seems 
that it only look what devices are present and load the needed kernel 
modules.

Maybe the following information will help to solve the Problem:

* On FreeBSD the system freezes when i insert the card and the kernel fire 
frequently messages of an "interrupt storm", and that it would throttle it. 
(That's the reason why I referred at the interrupt routing difference between 
lspci with the "special Intel"-detection Method and without. I'm not very 
familiar with lowlevel development and don't now whether this matters or 
not...)

If you think it could help to install a new kernel or you need some 
information or output, please tell me, it's no problem to install gentoo (or 
any other distribution) with a specific kernel (and maybe some patches)
