Public bug reported:

Affects: linux-source-2.6.15 linux-image-2.6.15-16-amd64-k8 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Upgrade from 2.16.12 in Breezy to 2.6.15-14/15/16 in Dapper
(amd64-generic/k8) broke the driver for the DVICO Fusion HDTV Plus.
Driver starts but the card cannot tune to any channels.

Investigation of source shows that drivers/media/video/cx88/cx88-dvb.c
has been altered at this point, from the version working in 2.6.12:

(2.6.15-16.23 version)

511                 dev->core->pll_addr = 0x61;
512                 dev->core->pll_desc = &dvb_pll_thomson_dtt7579;
513                 dev->dvb.frontend = mt352_attach(&dvico_fusionhdtv,
514                                                  &dev->core->i2c_adap);

line 511 should read as follows:

                 dev->core->pll_addr = 0x60;

A rebuild of the linux-image package with this change fixed the problem.
