It looks like the problem was with the standard vga=788 mode that at least
mandriva uses. When managed to switch to text mode, and used vga=ask and chose
the first mode , everything suddenly worked. It seems that Mandriva outsmarted
themselves (well at least me) with their installation routine. Sorry about the
alarm re the kernel itself. (and the console modes also now work--
alt-ctrl-F1-6).

I have now used the vga=ask kernel parameter and tried a large fraction of the VESA modes and
the VGA modes listed. (7 VGA modes F00-F03 F05-7 and 9 VESA modes
305 307 318 312 314 315 301 303 311) . None of the VESA modes I tried worked
. All of the VGA modes I tried work.
By work I mean display anything after the mode is selected
In the VESA modes the screen is
simply blank.-- no cursor, no nothing. In the VGA modes, text appears,
scrolling
by (various kernel reports during the startup). Ie, the kernel's handling of
the VESA modes on this system do not seem to work at all.
I have no idea if the fault lies within the kernel or whether Mandriva did
something to the kernel. Note again that the xorg drivers work fine, as X
works and displays.
