I'd like to add only that the video card is integrated on the mainboard.
Maybe that register disables the integrated video card. I don't know.
Anyway I must also point out that on FreeBSD that register is used only
for IBM_L40 PC.
That said now I know how to make linux work again on this PC.
Let's see what will happen when 2.2.18 will come out as the new stable kernel.

NB: the video card works without problems now. it's even found by lspci
(which couldn't find it before). I can also use any extended vga mode.
So the problem wasn't probably the video chipset.
