[Soekris] net48xx Error LED and detecting a 48xx under Linux

[Chris Boot]

Hullo,

Yep, I'm using scx200_gpio already, and as long as the error LED is accessed 
using minor 20 on the 4826 (I know it is on the 4801) then I'm doing well! :-)

If someone can confirm the above I'll rename my driver net48xx_led. Should be 
making its way to linux-kernel and here shortly.

Now if only there was a way of detecting a net48{01,26}...
