The field order selection is an ioctl extension of directfb's via
driver. So it is not available from via's own one.
Didn't find the chars "irq" in via's *.[ch] files ;-) .

So add these lines to the modes of your EN15000 system.

Did you choose tv_system=2 (PAL) as module load parameter ?
But there seems to be only a 60HZ definition:
bodega2 Linux-FBDev-kernel-src_2.6.00.03a # grep RES_720X576_ *.h
share.h:#define RES_720X576_60HZ_PIXCLOCK 30611
bodega2 Linux-FBDev-kernel-src_2.6.00.03a # grep RES_720X576_ *.c
hw.c: {720, 576, RES_720X576_60HZ_PIXCLOCK, 60},

With my epia system I only test VGA out as I've no TV in my pc room.
