Yes, it is the standard pc kernel. And I'm using vesa:

mouseport=ps2
monitor=vesa
vgasize=800x600x16

with a:

ATI Technologies Radeon 9200SE 5964 (rev. 0x01)

BTW, I had no problem before having to change the monitor. The new one
is a 20" LCD, and the thing can "decide" parameters on its own. With the
old monitor, I had not this...

Since the new monitor is also with "screen" ratio (1600x900), I wonder
if my untouched:

vgasize=800x600x16

can not be a problem (because I can also switch to scrolling and
resizing the window because lines wrap...). If the ratio is not to its
taste, there may be a buffer reserved for some size, with the hardware
(monitor/card) deciding for something else?
