It is actually a bug in the NetBSD bootloader which causes problems on
CompactFlash cards with ID "Toshiba THNCF064MBA".

The bootloader commands the BIOS to load sectors using Interrupt 0x13,
function 2. According to "Ralf Brown's Interrupt List," when function 2
indicates an error, you are supposed to call Interrupt 0x13, function
0, to reset the disk. The NetBSD bootloader does no such thing. LILO,
which always works, does.
