[ARMedslack] Trying armedslack-current

To make a long story . . . long . . .

I got my recompiled u-boot to recognize the micro SD card slot and boot off of 
it.  So instead of running my GuruPlug from a USB dongle with a 4 GB SD card I 
bought an 8gb micro to run the system.  So I am re-installing and testing with 
the latest stuff!  I can boot from USB and now the micro SD onboard.

The patch to u-boot changed the way in which the onboard device sorted out LUN 
access and now it shows up properly and now I can boot off the onboard micro SD 
card as there are really 2 devices there with only one physically present.


I run X windows from the Guru to my main Linux machine as display :2. :1 is for 
my second X display for World of Warcraft. :0 is my Slack KDE desktop. I only 
have a single core CPU on my desktop.  I wanted to offload my Bittorrents off to 
the GuruPlug that also runs my wifi network for my android phone and 
occasionally other friends laptops, etc.  It had been helping ALOT and working 
GREAT with 13.1 armedslack running Ktorrent remote NFSed to my main system 
saving all the data.  So I run the entire KDE desktop from the Guru every day 
displaying on my desktop PC.

I cannot run either of the dual gigabit ports on the GuruPlug because of the 
known overheating/rebooting issues.  (BAD BAD MARVELL!) I have to plug in a 
USB/ethernet to get me network access. It's sad, but it works.  I so wish 
Marvell could fix the overheating issue so I could remove all this dangling crap!

I ran into an issue with the kernel in -current.  It seems the guru kernel 
patches to include the wireless AP functionality are missing.  I cannot bring up 
the uap8xxx driver.
