This is what I get:

/home/user # ls -l /dev/mmc*
brw-rw---- 1 root floppy 179, 0 Dec 31 1969 /dev/mmcblk0
brw-rw---- 1 root floppy 179, 1 Dec 31 1969 /dev/mmcblk0p1
brw-rw---- 1 root floppy 179, 2 Dec 31 1969 /dev/mmcblk0p2
brw-rw---- 1 root floppy 179, 3 Dec 31 1969 /dev/mmcblk0p3

Oddly it has a strange date and year. Does it mean the N900 can atleast see the microSD but can't access it?

The WP7 device is formatted with CPRM:

Making the access to it require both a hardware layer and a software layer that supports it.

In the XDA forum someone said the Linux kernel has the software support required for detecting the microSD:
