I'm mostly clueless about the kernel beyond adding printk's, unfortunately. But I tried printing out the other values, and this is what I have so far: For 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI Robson CE [AMD Radeon HD 6300 Series] [1002:68e4] pci 0000:01:00.0: [1002:68e4] type 00 class 0x030000 pci 0000:01:00.0: reg 10: [mem 0xc0000000-0xcfffffff 64bit pref] pci 0000:01:00.0: reg 18: [mem 0xd0020000-0xd003ffff 64bit] pci 0000:01:00.0: reg 20: [io 0xd000-0xd0ff] pci 0000:01:00.0: reg 30: [mem 0xd0000000-0xd001ffff pref] pci 0000:01:00.0: supports D1 D2 (dbg) ------------------------------------- (dbg) old dev->rom: 0x0000000000000000, dev->romlen: 0 (dbg) new dev->rom: 0x00000000029ad058, dev->romlen: 61952 (dbg) pa_data: 0x00000000029ad018 + offset: 64 (dbg) data->type: 3, data->len: 62000 (dbg) rom->segment: 0, rom->bus: 1 (dbg) rom->device: 0, rom->function: 0 (dbg) rom->vendor: 1002, rom->devid: 68e4 <-- radeon (dbg) ------------------------------------- And for 05:00.5 Ethernet controller [0200]: JMicron Technology Corp.
