Here goes a good suggestion: do not forget to load the module, you
dumb ass! Now I got this:

sdhci0: <RICOH R5C822 SD> mem 0xe4103000-0xe41030ff irq 19 at device 6.3 on pci2
sdhci0: Reserved 0x100 bytes for rid 0x10 type 3 at 0xe4103000
sdhci0: 1 slot(s) allocated
sdhci0: [MPSAFE]
sdhci0: [ITHREAD]
mmc0: <MMC/SD bus> on sdhci0

Much better. However, I got a system crash and reboot attempting to
unload the module.
