If the kernel cannot find any partitions, it could be because any of the
following configuration options are missing :
- disk controller handling (depends on your hardware)
- disk handling (BLK_DEV_SD as sdb is an SCSI-style disk)
- partition table handling (usually MSDOS_PARTITION on PC)

Yes. The only useful udev feature I needed on that system was firmware
loading, but I implemented it with a simple shell script as /sbin/hotplug.

No, the static /dev was populated by default.

Nothing worth mentionning, I guess. Just root=/dev/sda1 on the kernel
command line.
