SCO Herc support Bug?

[Jim Morton]

The following patch can be applied to 386 2.2.2 and 2.2.3 kernels
to fix the Hercules graphics mode reset bug. The cause of the bug
was that the reset values for Nrow and Ncol were swapped. (Nrow
should be 0x19 = 25 decimal, Ncol should be 0x50 = 80 decimal).

	# adb -w /xenix -
	* cnioctl+0x522?x
	_cnioctl+0x522: 0x50
	* cnioctl+0x522?w 0x19
	_cnioctl+0x522: 0x50=   0x19
	* cnioctl+0x52c?x
	_cnioctl+0x52c: 0x19
	* cnioctl+0x52c?w 0x50
	_cnioctl+0x52c: 0x19=   0x50
	* $q
	# cd /
	# sync;sync;reboot

Disclaimer: this is my fix, not SCO's. SCO's is called release 2.3.1.
