I'm running a FreeBSD 5-CURRENT snapshot from Dec. 5, and trying to 
configure an AmbiCom Cardbus ethernet card (a DEC Tulip base).  I've 
included cardbus, pccbb, miibus, and dc in my kernel, and enabled use of 
DHCP.  Since I haven't tracked -current since 4.x split off from it, I had 
a great deal of FM to R before I realized things like there's a file called 
/boot/device.hints that's very important.  Putting


into /boot/device.hints made the "watchdog timeout" errors I had been 
getting on boot go away, but the card still didn't work.  Do I need to 
specify drq or maddr, and how would I determine if 0x300 is the right 
port?  This may be due to the fact that it looks like my graphics card and 
my ethernet card are both assigned IRQ 11 (see clip from dmesg below).  But 
I really have no idea how to use device.hints or even how to set up an 
ethernet card under FreeBSD (I know, I should have picked something other 
than cardbus on -current for my first experience), so any help would be 
appreciated.  Thanks!

then I got "watchdog timeout" errors.
