I haven't used 2.6 so far, I'm fine with 2.4.25

I'm using a vanilla kernel, with ALSA sound drivers.

http://directfb.org/cgi-bin/cvsweb.cgi/linux-fb/

As a module.

No, don't do that. vesafb will grab you gfx adapter.

If you plan to compile DirectFB with multiapplication core, you'll need 
fusion:

Bleeding edge CVS. ;-)

FusionSound is mandatory, so is libavcodec. I'm still using 0.4.8

I'm using:

mode "720x576-50Hz-16bit"
    geometry 720 576 720 576 32
    timings 31208 144 40 32 10 128 3
    bcast true
endmode

My startup looks like this:

# DirectFB multiapplication core
modprobe fusion

# viafb + set right mode
modprobe viafb refresh=50 mode=720x576 TVon=1 TVoverscan=1 bpp=32
fbset -a "720x576-50Hz-16bit"

# video overlay covers all other layers, so don't use it directly
# (otherwise no translucent windows with vdr)
export DFB_CLE266_UNDERLAY=1

# DVB drivers
modprobe bttv i2c_hw=1 card=0x71
modprobe dvb-bt8xx
modprobe dst
