Same problem affects both of these suggestions - the microSD is located
inside the phone battery compartment, under the battery.  There's likely
no room for ANYTHING unless you snake some flextrace or wires around the
body of the battery.

There's been a use for SDIO with linux.  Several handhelds with SD slots
either ship with or can support linux.  The Zaurus for example.  - A company in India
has ported their proprietary SDIO linux stack to the factory Zaurus
distro.  (EmbWise's SDIOWorx)  But nothing GPL - the SDIO specification
is still too tightly controlled/licensed/restricted.
