[PATCH] The scheduled removal of some OSS drivers

This patch contains the scheduled removal of OSS drivers that:
- have ALSA drivers for the same hardware without known regressions and
- whose Kconfig options have been removed in 2.6.17.

- *	ALI  ali5455 and friends ICH driver for Linux
- *	LEI HU <Lei_Hu@ali.com.tw>
- *
- *  Built from:
- *	drivers/sound/i810_audio
- *
- *  	The ALi 5455 is similar but not quite identical to the Intel ICH
- *	series of controllers. Its easier to keep the driver separated from
- *	the i810 driver.

- *
- *	ALi 5455 theory of operation
- *
- *	The chipset provides three DMA channels that talk to an AC97
- *	CODEC (AC97 is a digital/analog mixer standard). At its simplest
- *	you get 48Khz audio with basic volume and mixer controls. At the
- *	best you get rate adaption in the codec. We set the card up so
- *	that we never take completion interrupts but instead keep the card
- *	chasing its tail around a ring buffer. This is needed for mmap
- *	mode audio and happens to work rather well for non-mmap modes too.
- *
- *	The board has one output channel for PCM audio (supported) and
- *	a stereo line in and mono microphone input. Again these are normally
- *	locked to 48Khz only. Right now recording is not finished.
- *
- *	There is no midi support, no synth support. Use timidity. To get
- *	esd working you need to use esd -r 48000 as it won't probe 48KHz
- *	by default. mpg123 can't handle 48Khz only audio so use xmms.
- *
- *	If you need to force a specific rate set the clocking= option
- *
