The kernel rewrite is going well.
Finished the block device manager and cache.
The RTC driver is working as well (smallest driver in the whole OS)
The FAT32 driver is also shaping up quite well.
The module manager is up and running, and thus all drivers are now separate modules (with the exception of the SDHC and the FAT32 drivers, since they are needed to read the card and thus to load further modules. This requirement will eventually go away, as the bootloader will be modified to load the default block device and default filesystem drivers into ram by itself.
