I have a via embedded MII board with the 600 Mhz fanless chip.  I have
seen the power errors on this, but they never occur if the card is in
there when its booted.

A more pressing problem is the GC83 sony ericsson card I have hangs
after a short time of usage, but I think that is the cards fault.  (You
can use the card again after a cardctl reset.  I'm using the latest
mm-sources in portage.)  If anyone thinks it may be related please let
me know.  

I have contacted ericsson to try to get the older firmware again which I
believe worked better, but they flat out refuse to give it to me and
their firmware updater simply updates it to the newest with no prompts
or options to save anything.

If anyone wants more info about this board or for me to try a patch then
let me know.  I may try some of the offered patches for the pcmcia
controller anyway, in the event it really is related somehow.

-Robert
