        After the last "cvs update" new kernels crash while attaching
        pnpbios devices (at least on my machine).
        Changing sys/arch/i386/pnpbios/pnpbios.c from 1.63 back
        to 1.62 makes the kernel work again.

The crash happens in cfdriver_get_iattr. The last pnpbios function that
can be seen in the backtrace is pnpbios_attachnode. If needed, I can
connect a serial console and provide a ddb traceback.

normaly the kernel continues with: 
com0 at pnpbios0 index 1 (PNP0501)
com0: io 3f8-3ff, irq 4
com0: ns16550a, working fifo
lpt0 at pnpbios0 index 2 (PNP0401)
lpt0: io 378-37f 778-77f, irq 7

        <precise description of the problem (multiple lines)>
        Boot with src/sys/arch/i386/pnpbios/pnpbios.c 1.63 on a 
        Dell Optiplex SX260.
        Use src/sys/arch/i386/pnpbios/pnpbios.c 1.62

        <Please check that the above is correct for the bug being reported,>
        <and append source date of snapshot, if applicable (one line).>
