21.1Swiz
31.1Swizo check for a possibility to replace remaining vtophys()
41.1Swizo clean up whitespace before and after braces ("( " -> "(")
51.1Swizo clean up bt8xx.h
61.1Swizo replace vm_offset_t (still any left?)

91.1Swizo use NetBSD's own i2c-functions
101.1Swizo look for cause of warning (without consequence, as far as I can

121.1Swiz  bktr0: ioctl: tsleep error 35 200001c
131.1Swizo split up contents of bktr directory to better places? (also fix
141.1Swiz  bktr2netbsd in that case)
151.1Swizo use NetBSD PCI listings for recognition of cards.
161.1Swizo write man page
171.2Swizo remove #ifdef'd FreeBSD/OpenBSD code (?)
