[linux-dvb] Twinhan SatExpress PCI, dst_probe: unknown device

[PAVEL TKATCHOUK]

Motherboard - VIA Epia M10000, OS - epiOS. I'm new to linux-dvb so started
from making sure board works on XP Pro (box is dual-bootable). Booted to
epiOS and modprobbed dvb-bt8xx, dmesg looks good. nscan was able to scan
12224 on Echostar-148, generated channels.conf, looks good too. szap 
lockked on FTA channels just fine.

Than I tried to see if I can actually watch the signal, that's when 
disaster strikes:

./szap -c channels_Echostar_148_szap.conf -l DBS -r "PAEC" & 
xine stdin://mpeg2</dev/dvb/adapter0/dvr0 

After that screen went black, than fall back to login dialog covered by 
green rectangular. After reboot card is not recognized anymore: 

dst_probe: unknown device 
frontend_init: could not find a Twinhan DST 
dvb_bt8xx: a frontend driver was not found for device... 

Made few reboots, including cold one, same results.

Reboot to Windows (same box), ProgDVB shows signal level/quality but no 
picture (same FTA PAEC channel) and in properties shows bitrate but no 
frame rate or width/height. 

Run TwinhanDTV, rescan sat, lousy DTV detected only ~40 channels, switch 
to some FTA (Dish info or something), voila - got picture! 

Reboot to epiOS, modprobe dvb-bt8xx, got the same "frontend driver was not 
found" :-( 

Read somewhere that acpi=off might help here, but I don't know how to pass
it to the booting epiOS. 

Below is dmesg in case somebody's willing to help:
