Hi,
I find a solution for my old satellite PCI DVB-S card with chipset SAA7146 on a system with LinHES 8.2 plus updates (mythtv 0.27.4-3, LinHES-system 8.2-5).
(My dual port DVB-S2 card " Micronas Semiconductor Holding AG nGene PCI-Express Multimedia Controller (rev 01)" have no problem with standard installation of LinHES 8.2)

The problem is, that this card is not showing as a DVB-S satellite card, the following error message:
dmesg |grep -i dvb
Code:
 Linux video capture interface: v2.00
cx88/2: cx2388x dvb driver version 0.0.9 loaded
 cx88/2: registering cx8802 driver, type: dvb access: shared


To fix this you must edit the file
/etc/modprobe.d/alsa-base.conf and put a "#" in the line "options cx88_alsa index=-2" and reboot your system.
Code:
# Prevent abnormal drivers from grabbing index 0
options bt87x index=-2
#options cx88_alsa index=-2
options saa7134-alsa index=-2
options snd-atiixp-modem index=-2
options snd-intel8x0m index=-2
options snd-via82xx-modem index=-2
options snd-usb-audio index=-2
options snd-usb-usx2y index=-2
options snd-usb-caiaq index=-2

This is for information only:
**********************************************************************************************
I have a old "TechnoTrend TT Budget S-1500 PCI" DVB-S satellite card.
I) This is the error without the changes in /etc/modprobe.d/alsa-base.conf
1) "lspci -vv" show
Code:
01:05.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
        Subsystem: Technotrend Systemtechnik GmbH Device 1017
        Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-

        Interrupt: pin A routed to IRQ 15

2) dmesg |grep -i dvb

 cx88/2: registering cx8802 driver, type: dvb access: shared

3) You have no device in /dev/dvb/

II) After the changing the /etc/modprobe.d/alsa-base.conf and reboot the system you can see
1) lspci -vvv
Code:

2) dmesg |grep -i dvb
