Hm, then the chip isn't reset for some reason.

Ok, how about the following sequence (setting also bit 0 in the EC register):

v=$(outb 0x66 0x80; outb 0x62 0x1a; inb 0x62)
echo $v
outb 0x66 0x81; outb 0x62 0x1a; outb 0x62 $(( v | 9 ))
outb 0x66 0x80; outb 0x62 0x1a; inb 0x62

Is the display still enabled?
