Bug 28182

When using the 5450 card and trying a 640x480 interlaced console frame buffer I get half the screen shown (top half) and bottom is out of the screen display.  It's a progressive picture too, not interlaced.  If I use 320x240 progressive it all fits, so seems to be that the interlacing isn't working for this chip.  Not sure if it's known and just not been implemented yet or if it's a bug. 

Thanks,
Chris
