Since i use 2.4.18-ac i'm oblige to rebuild the map file in my /boot partition after having used ext3 and raw device on other partitions /dev/hda2: /boot /dev/hda5: /root /dev/hda6: raw /dev/hda7: a partition written through ext3 journaled mode I don't know why ? It seems the map file is corrupted ( LIL- output given by LILO). This is reproductible, but i never get that with 2.4.14 for instance. If somebody as an idea it will be welcome. For your problem, you said the application uses a negative addressing on raw device. How this is possible, as raw interface is ( pseudo device name, byte offset) ? Do you mean that negative offset values are accepted ?
