FreeBSD's tftp and tftpd-hpa

FreeBSD's current tftp client doesn't work with tftpd-hpa.

FreeBSD 9.0-CURRENT (XEN) #0: Fri Jan 21 15:54:41 EST 2011
~(fbpv)1% tftp
tftp> get pxeboot
Got ERROR packet: Unsupported option(s) requested
Error code 2048: Unsupported option(s) requested

Anybody got a solution for this? Otherwise I'll hack it up.

I'm forced to use tftpd-hpa because I have diskless Linux clients that
are brought up with pxelinux.0 and that one needs the option to
provide file size beforehand.  But FreeBSD's tftp client wants other
options and KABOOM.

The bad thing about this is that I'm debugging probably unrelated
problems with pxeboot and I have no way of knowing for sure whether my
problems might be caused by more options clashes.  It's not that
tftpd-hpa log which options specifically were requested and denied.
Or that FreeBSD's client says which options it requested before it
blew up.
