Problem with new bwn driver on -CURRENT

I was extremely pleased to see this driver, so I could get off of the
flaky NDIS version.  I have a Dell Vostra 2510 with a LP bwn mini-PCI
card.  I have set if_bwn_load="YES" in /boot/loader.conf.  I also have
bwn_v4_lp_ucode_load="YES" set.

The firmware and driver loads.  However, if_bwn doesn't attach to the
card.  Once the OS is fully booted, I kldunload if_bwn, then reload it,
and the driver attaches just fine.  Once it is attached, however, I can
pass traffic just fine, but I get a large number of these messages on
the console, and the traffic rate is not what it was with the NDIS
driver:

bwn0: out of bounds of the square-root table (-770884)
bwn0: out of bounds of the square-root table (-225625)
bwn0: out of bounds of the square-root table (-240100)

When I boot with verbose mode, I only see the siba driver attach to the
card:

siba_bwn0: <Broadcom BCM4312 802.11b/g Wireless> mem 0xf4000000-0xf4003fff irq 19 at device 0.0 on pci6

My pciconf output is:

siba_bwn0_at_pci0:6:0:0:   class=0x028000 card=0x000b1028 chip=0x431514e4 rev=0x01 hdr=0x00
    vendor     = 'Broadcom Corporation'
    device     = 'Broadcom Wireless b/g (BCM4315/BCM22062000)'
    class      = network

When the driver does attach, I see:

bwn0 on siba_bwn0
bwn0: WLAN (chipid 0x4312 rev 15) PHY (analog 6 type 5 rev 1) RADIO (manuf 0x17f
bwn0: DMA (64 bits)
bwn0: MSI count : 1
siba_bwn0: attempting to allocate 1 MSI vectors (1 supported)
msi: routing MSI IRQ 258 to local APIC 1 vector 54
siba_bwn0: using IRQ 258 for MSI
bwn0: Using 1 MSI messages
bwn0: [MPSAFE]
bwn0: [FILTER]
bwn0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
bwn0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36M
bps 48Mbps 54Mbps
wlan0: bpf attached
wlan0: bpf attached

Am I missing anything to get this to attach at boot time?  Thanks.

Joe
