No.  There is already an open bug report for this problem (see

Hmm ... I don't know.  I have gcc 2.95 installed on my system, which was
used to build the pcmcia-modules-2.2.18 package.  I don't know what
Herbert Xu has used to build the kernel-image-2.2.18 package.  He has
not responded to my email regarding this problem.

One thing is clear.  I'm doing something different to build the PCMCIA
modules than was done to build the kernel image.  For example, I think
that you can get Debian's PCMCIA modules to work if you rebuild the
kernel-image package yourself.  At least, I've had no trouble building
PCMCIA modules against kernel images that I have built myself, only
against the official Debian kernel.

Well, that only works if the appropriate kernel version has already
been installed, something that the pcmcia-modules package cannot
ensure.  Certainly, I can guarantee that the currently running kernel
is installed; therefore, I call "depmod -a" if the modules match this

If the modules accompany another kernel, then the system will need to
be rebooted to use the kernel in question.  Therefore, I think that
it should be the kernel package's responsibility to ensure that the
dependencies have been created.

If you have any creative ideas to better handle this problem, please
share them.
