[realtek] Startech ST100SLP LowProfile 8139 for a Dell LowProfile box

[Dean Blankenship]

Have installed other Startech ST100SLP in other machines and they work
fine.  This instance does not.

The one point which jumps out is that the EEPROM contents are read
as 0x00, all bytes/words.  Tx & Rx are also disabled but considering
it never really got configured ... not surprising.

1) dmesg does not report finding the card (the builtin Broadcom is
    discovered and is eth0 as it should be).
2) kudzu discovers the card and configures networking.
3) lspci sees the card (indicates IRQ is shared with the Broadcom card)
4) "modprobe eth1" does 'cause' the card to be discovered (now present
    in 'dmesg'), "ifup eth1" doesn't work until "ifdown eth1" then
    "ifup eth1" (i.e. again).  MAC address is 00:00:00:00:00:00 though,
    there is now IP address and it is not really working.

I've attach "lspci", "lspci -nvvs 4:0", "rtl8139-diag -aeem" output
