Interlaced video with atyfb?

(My apologies if this has been posted twice)

Hi,

I'm running the 2.4.19 kernel with atyfb on a Mach64VT card.

This all works fine:-

/usr/src/linux# fbset -v
Linux Frame Buffer Device Configuration Version 2.1 (23/06/1999)
(C) Copyright 1995-1999 by Geert Uytterhoeven

Opening frame buffer device `/dev/fb0'
Using current video mode from `/dev/fb0'

mode "640x400-70"
    # D: 25.157 MHz, H: 31.446 kHz, V: 69.879 Hz
    geometry 640 400 640 3251 8
    timings 39751 40 24 39 9 96 2
    accel true
    rgba 8/0,8/0,8/0,0/0
endmode

but I cannot switch interlaced video on:-

/usr/src/linux# fbset -laced true
ioctl FBIOPUT_VSCREENINFO: Invalid argument

Checking the newsgroups I see other people have similar problems.

Any ideas?

Steve.
