It certainly is, I moved it from the XP2800+ box to the 64-bit AM2 box 
and lspci now says.
01:08.0 Multimedia video controller: Conexant CX23880/1/2/3 PCI Video 
and Audio Decoder (rev 05)
01:08.2 Multimedia controller: Conexant CX23880/1/2/3 PCI Video and 
Audio Decoder (rev 05)

01:08.0 Class 0400: 14f1:8800 (rev 05)
01:08.2 Class 0480: 14f1:8800 (rev 05)

Something relating to PCI-IDS from openSUSE did cross my mind. At some 
stage it looks like the x86 also failed to autodetect the card after a 
pci-ids change.
# rpm -ql pciutils-ids|less
/usr/bin/merge-pciids
/usr/bin/merge-pciids.pl
/usr/share/pci.ids
/usr/share/pci.ids.d

# grep -i kworld /usr/share/pci.ids
                 1131 0000  KWorld V-Stream Studio TV Terminator
                 17de 08a1  KWorld/VStream XPert DVB-T with cx22702
                 17de 08a6  KWorld/VStream XPert DVB-T
                 17de 08b2  KWorld DVB-S 100
                 17de 08a6  KWorld/VStream XPert DVB-T

Regards
Sid.
