It is a hack, it can't be included in any official firmware. Even OMAP2 in N8x0 does not support high speed SD and MMC modes officially (= with TI's blessing) so those are disabled in kernels shipped by Nokia. OMAP1710 in 770 is older and maybe they also used other incompatible parts or design since they intentionally restrict 770 mmc speed to 12MHz in all 770 kernels (24Mhz would be normal, 48MHz is high speed). Or maybe 770 is fine but rs-mmc cards on market are flaky so they slowed it down to make it more compatiblle, who knows.
