However, lspci (and the specs) shows that my board is i945.
00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML
and 945GT Express Memory Controller Hub (rev 03)
(Mobile Intel® 945 PM Express Chipset + ICH7M)

Already have a programmer (lpc/fwh/etc) and think i have a i945 and a
Ill try to get the debug device, and try your suggestions.
