You have a MACH64 video card, which violates the standard for the IBM graphics card it is attempting to emulate by listening to port 0x3e8 when it has not been put in a specific mode that requires this. In other words, MACH64 cards are broken. You can work around the problem in two stages: 1) a) At the boot prompt, type "-c" and hit return b) At the next prompt, type "visual" and hit return c) Disable the SIO (serial port) driver. The conflict is with the SIo probe for COM3. d) Install normally. 2) a) Modify /sys/i386/isa/sio.c to remove 0x3e8 b) Rebuild and install a new kernel c) Reboot. Your serial ports, other than COM3, will once again be active. This is described in the handbook and in the 2.1R FAQ. It is fixed in more recent install snapshots by disabling com3 to start with.
