The SCR and EXT_CSD are both the only data transfers that are done in
1-bit mode in the respective init paths. Are you sure that hack you
have for ACMDs is really for ACMDs and not for 1-bit transfers?

(And you're right about me not liking that hack, but I can let that one
slide as long as you agree it is important to get rid off ;))

Yeah, it works for older MMC cards. The newer, larger ones will fail
when it can't read the EXT_CSD though.
