This evning i decided to give it a try.

For a starter, my laptop is a Lenovo 3000 N100 (<LENOVO TP-61> according to acpi).

This are some of the hard facts.

Getting src/sys patched up was somewhat easy. There is one small problem though.

The function ' bus_setup_intr()' has lately changed the number of arguments.

after looking at some other drivers i decided to try and just add NULL,.

It compiled then, even loaded as a module.

sdh0: <SD Host Controller> mem 0xb0300400-0xb03004ff irq 23 at device 6.1 on pci5

sdh0: Found 1 slots

sdh0: [ITHREAD]

Everything looks fine.. atleast till i decide to hotplug a sd card .. whoops reboot no panic.

Debugging will continue later..
