Seems to be the only way atm, but I will be watching... NetBSD has a Device Driver Writing Guide: http://www.netbsd.org/Documentation/kernel/ddwg.html Also, see the 'FreeBSD Kernel "Newbies"' thread in http://lists.freebsd.org/pipermail/freebsd-drivers/2007-December/date.html I am not a FreeBSD device driver writing wizard, but I gather the usual method is not to port a linux driver (due to massive differences between the linux kernel and the *BSD kernels, and also due to concerns with the quality of linux code), but to write a new driver. Data sheets and linux driver source are useful for learning how the device works.
