On resume, I need to a) close the lid and open it, b) run setfont to 
clear the garbage off the screen and make the text readable, and c) run 
kbdrate to reset the keyboard rate.

Problems: USB doesn't work after resuming. After plugging in a USB 
mouse, all I get is:

drivers/usb/host/uhci-hcd.c: bf80: host system error, PCI problems?

Also, artsd and suspend just don't cooperate well.
