Well, being neither their customer nor a kernel developer, I'm not sure 
my request would be considered serious. Anyway, probably I'll give it a 
try a bit later when I have an opportunity to dismount this board for 
more comfortable testing. I was also going to try to modify its BIOS to 
remove some unwanted behaviour unrelated to IRQs, and it might happen 
that I also discover something about PCI handling along with (It is just 
64k size, after all, and I have a 8086 debugger)


Thank you,

Regards,
Nikolai
