I've finally committed my PCMCIA bus support in the stage1. It browses the /sys/bus/pcmcia/devices/ sysfs directory to list devices, and use their modalias and prod_id* fields.

The device listing seems to work when the PCMCIA subsystem is initialized before stage1 is started, but some strange bugs appear when the stage1 program does the whole initialization (controller module loading, socket startup, device module loading). The pcnet_cs module hangs when inserted in the kernel... It's quite weird since it works fine when udev runs the same actions.

I suspect some kernel bug in our cooker 2.6.14 kernel package (yes, that's damn outdated), I've yet to try a more decent one.
