Device Hints vs. FreeBSD 4.10 Release

[Lonnie Santella]

I've switched from FreeBSD 5.2 to FreeBSD 4.10 Release. I've lost the 
ability to edit the /boot/device.hints file, since it no longer exists in 
ver 4.10. This is critical to me since I need to add the mouse flag:

hint.psm.0.flags="0x100"

This turns off the sync check which is what causes my mouse to jump all over 
the screen when I wiggle it. It's a PS/2 mouse - but plugged in via a 
Avocent 8-port KVM switch.

Is there another way to implement this type of port flag?

Thanks,

Lonnie
