[LinuxBIOS] Maybe a help for others: How to identify interrupt routing

[Juergen Beisert]

Hi,

attached a small text how to identify routing in an unknown system to create a 
pirq table, when there is no other chance to read it back from BIOS. Its 
Geode-GX1 specific, but maybe could help on other platforms also. Comments 
are welcome.

Regards
