Subject: [PATCH 2.6.18] declance: Support the I/O ASIC LANCE w/o TURBOchannel

 The onboard LANCE of I/O ASIC systems is not a TURBOchannel device, at 
least from the software point of view.  Therefore it does not rely on any 
kernel TURBOchannel bus services and can be supported even if support for 
TURBOchannel has not been enabled in the configuration.

Signed-off-by: Maciej W. Rozycki <macro@...ux-mips.org>
---
 Tested with the onboard LANCE of a DECstation 5000/133.

 Please apply.
