FreeBSD 6 Released BTX loader issue

I'm trying to have clean install FreeBSD 6.0 released in my X41 thinkpad by
using the cd, however I have problem while booting it in thinkpad X41 when I
load it using usb combo drive. The BTX loader keeps looping and halted
someway and I have actually seen this report from previous post but it is
not yet been fixed even till the FreeBSD 6.0 release.

I would like to know the status and what's actual problem or is there any
workaround.

Thanks
