To use my previous patch (wistron_btns support for fujitsu-siemens amilo
pro edition v3505) with my laptop, I need to make the wistron module
compile for x86_64. It is based on Linux 2.4.24-rc4 too.

NAK.

You cannot make 32 bit BIOS calls in a 64 bit OS.

This will (and does) segfault on x86-64 (tested on my Aspire 5020, where  
call_bios wistron-btns just segfaults on x86-64 with this patch).

This is a known issue, and the reason why wistron-btns (and the out-of-tree 
acerhk) have not been ported to x86-64.

Yes, in theory, this must segfault on x86-64.

In pratice, there is one laptop where it seems to works (no problem
for 3 weeks). A good reason to find why.
