Nope. I tried, but this is a problem with firmware that says there is 159
blocks per track, 5 heads and only 793 blocks per cylinder (while 159 * 5 is
795). AmigaOS' FFS handles it just ok, AFS thinks that there's 795 blocks
per cylinder, overestimates size of the partition and overwrites beginning
of the next one.

What NetBSD does is unknown to me, perhaps there is someone who knows... I
guess patching the kernel to calculate number of blocks per cylinder
correctly wouldn't be that difficult, but there may be more to it that just
the number of blocks...

Some guy from Australia who suffers from similar problem was bugging
Quantum, but they said he needed to send the disk for replacement. :( Not so
easy...
