* If this is a 3c905B, we have to check one extra thing.
* The 905B supports power management and may be placed in
* a low-power mode (D3 mode), typically by certain operating
* systems which shall not be named. The PCI BIOS is supposed
* to reset the NIC and bring it out of low-power mode, but
* some do not. Consequently, we have to see if this chip
* supports power management, and if so, make sure it's not
* in low-power mode. If power management is available, the
* capid byte will be 0x01.
*
* I _think_ that what actually happens is that the chip
* loses its PCI configuration during the transition from
* D3 back to D0; this means that it should be possible for
