Depends on what you call straight-forward: you can search for glamo_mci.sd_max_clk , a description can for instance be found at http://docs.openmoko.org/trac/ticket/1743 : Basically you need to set this variable in the u-boot environment - I reduced it even down to 5000000 , but more might also work - ymmv. Whether setting this through /sys parameter works I do not know - does anyone know? Stefan
