(2.6.16-rc1) It is an 'internal' bitmap, or is the bitmap in a file? If the bitmap is in a file, you need to me sure that the file is provided by mdadm when the array is assembled - using in-kernel autodetect won't work. If it is an internal bitmap.... it should work. Are there any kernel messages during boot that might be interesting?
