My mistake: I meant ide. I'd started this work looking into the libata.c 
block driver but realized later that it wasn't what I needed, but the 
term stuck in my mind. I'll fix references to mention IDE instead.

Will this be ok?

	/*
	 * ED Mini V2 [...]
	 * disable [...]
	 */

	/* mask for [...] */

Will do. Would CONFIG_IDE_USE_INSW_OUTSW do? Basically, that's what the 
test is for: either use outsw()/insw() or use outw()/inw() within a loop.

Note that this change does not relate per se to my patch and requires 
addition of this #define to a lot of config header files. Wouldn't it be 
better if I submitted it as an independent atomic patch?

I'll put them in two separate patches, one for fixing typos and one for 
adding the CONFIG_SKIP_LOWLEVEL_INIT comments and line.
