Preliminary: Soekris 4501 + Wistron CM9

[daniel]

I've been using a Net 4501 for several years now (since at least  
OpenBSD 3.8) with no problems. I've recently added a mini-PCI Wistron  
CM9 (ath 5212). Very soon after bringing the interface up, I get all  
sorts of channel reset and wake up errors.

Before I start going crazy with posting all sorts of diagnostic info,  
I'm wondering if the first thing I should look at is my power supply.  
I've used a 12V 1.2A since the beginning, but have not ever used the  
PCI or mini-PCI slots.

Could my Net 4501, with the addition of the mini-PCI card, now be  
starved for electrons?
