 - if you get repeated `atapi_poll called!' console messages with FreeBSD
 guests or other weird cdrom problems then thats probably because the guest
 has atapicam loaded, which for reasons still to be determined has problems

+- perhaps it should be noted that if you want to use qemu with -m 512
+or larger on i386 hosts you need to increase the kern.maxdsiz tunable
+in loader.conf(5) since the default is 512 MB, and qemu needs memory for
+itself also.
+- kqemu seems to be broken on amd64 SMP hosts atm (causing the host
+to panic), if this affects you you can either use an UP host kernel as a
+workaround or disable kqemu.
 - qemu now uses aio at least for ide dma, so if you get `Invalid system call'
 crashes that is because aio is not (kld)loaded.
