Sorry if this shows up twice; I seem to be having a local partial outage
of some sort.

The TS-7200 manual says:

The Ethernet PHY chip can be powered down, under software control, to save
approximately 90 mA of current consumption. This is controlled by the 
EP9302 Digital output on Port H, bit 2. A logic zero will power down the
KS8721 PHY  interface.

Before I go reinventing the wheel, is there a /sys or /proc interface 
that lets me do this?  I am running 2.6.29 with Mattheiu Crapet's patches.

Also, I have the 2x24 LCD display.  The technologic website has no 
documentation on this.  Anyone know if there is a way to turn off the 
backlight or to power it down under software control?

Thanks,

--Yan
