The patch also will show more information like > whether the controller runs in PCI mode or not as well as showing > frequency of PCI clock speed. I've applied the patch. Now dmesg shows: bge0: <HP NC7782 Gigabit Server Adapter, ASIC rev. 0x002100> mem 0xfdf70000-0xfdf7ffff irq 25 at device 2.0 on pci2 bge0: CHIP ID 0x00002100; ASIC REV 0x02; CHIP REV 0x21; PCI-X 66 MHz I'll watch on Ierrs counter.
