ATI TV Wonder regression since at least 3.19.6

Hi,

	my wonderfully old ATI TV Wonder (PCI ID 14f1:8800, module cx8800)
	does not behave properly since I upgraded from Linux-3.18.6 to
	Linux-3.19.6 (Gentoo builds).

	I usually spawn MPlayer to use that device; when I use it under
	3.19.6, I get an image like the one that's attached and the usual
	sound loopback that goes from the TV card to my sound card does not
	seem to be functioning.  Booting with 3.18.6 makes everything work
	again.

	After a cold boot, with 3.18.6, the first use of the TV card seems
	to provoke some kind of initialization (image takes like 0.5 seconds
	to settle), with 3.19.6, I immediately get the broken image.

	Nothing in `dmesg` would indicate something's horribly broken.

	What kind of debugging output would be useful to you guys so we can
	identify the issue?


	Thanks,
