I haven't tried(or needed to) raid recovery with raid 0.90
but I have with raid 0.36(raid1). This uses normal linux partition
types instead of fd, one of my drives died and I switched
lilo and friends over to the seocnd disk, disabled raid and continued
to use the system for another few months till the 2nd disk died.

with raid 0.90 it may be different, what does cat /proc/mdstat
show when you only have 1 disk?  also be sure you have raid support
on that floppy, the new raid may "need" it to access the disk(perhaps
it is in a slightly different format which the raid tools provide
transparent access to).
