Hi folks...

Well, while waiting for a 1.1 pre-release to build on my hp300, I decided 
to look into why screenblank(8) and Xsun don't blank my 4/260's bwtwo.  I 
was wondering if the mouse, et. al. were reporting constant activity, but 
that's not the case...

It turns out that FBIOSVIDEO isn't doing anything on my system:

	case FBIOSVIDEO:
		if (*(int *)data)
			sc->sc_reg->bw_ctl |= CTL_VE;
		else
			sc->sc_reg->bw_ctl &= ~CTL_VE;
		break;

That bit, CTL_VE (0x40 in the bw_ctl register) doesn't seem to have any 
effect.  Now, I'm wondering, are my bwtwo registers a) being mapped 
incorrectly, or b) "different"?  If they're being mapped incorrectly, I 
wonder what I'm frobbing?

Ideas, anyone?
