o Properly use rman(9) to manage resources. This eliminates the need to puc-specific hacks to rman. It also allows devinfo(8) to be used to find out the specific assignment of resources to serial/parallel ports. o Compress the PCI device "database" by optimizing for the common case and to use a procedural interface to handle the exceptions. The procedural interface also generalizes the need to setup the hardware (program chipsets, program clock frequencies). o Eliminate the need for PUC_FASTINTR. Serdev devices are fast by default and non-serdev devices are handled by the bus. o Use the serdev I/F to collect interrupt status and to handle interrupts across ports in priority order. o Sync the PCI device configuration to include devices found in NetBSD and not yet merged to FreeBSD. o Add support for Quatech 2, 4 and 8 port UARTs. o Add support for a couple dozen Timedia serial cards as found in Linux.
