I am using:

options        KVM86                   # required for vesabios
vesabios*      at vesabiosbus?
vesafb*        at vesabios?
options        VESAFB_WIDTH=1024
options        VESAFB_HEIGHT=768
options        VESAFB_DEPTH=16
options        VESAFB_PM               # power management support
wsdisplay*     at vesafb? console ?

When at the text console, it displays very slow. If I output a screen full 
of text, I can watch it type line by line. Maybe two seconds to fill the 
screen. (It is like I am on a slow serial console.)

Any suggestions on how to speed this up? Or troubleshoot this?

By the way, I also use this under X (since around May) and it is fast 
enough for me there. Displaying same text in an xterm in X using wsfb with 
wsdisplay with vesafb is very fast. It just flashes on the screen like I 
expect.

Anyone else have very slow text console display?
