Broadcom wireless module doesn't load at boot time

[sas3]

Despite following the steps as best as I could, Broadcom hybrid_wl module doesn't seem to load at boot time:
I did a fresh install of Kubuntu 9.10 on my Dell Inspiron 1525. The WLAN drivers didn't work out of box. So I followed the instructions at Broadcom's site, doing the following:
1. Found ssb and b43 modules loaded; removed them (rmmod).
2. Didn't find any wl drivers preinstalled; so nothing to do there.
3. Created a directory /lib/modules/2.6.31-14-generic/kernel/drivers/net/wireless/hybrid_wl/ and copied the broadcom "wl.ko" file ("make"d as per instructions from their download) there.
4. Did a "sudo depmod"
5. Added the lines "blacklist ssb" and "blacklist 43" at the end of /etc/modprobe.d/blacklist.conf; in that order
6. Did a "sudo modprobe wl"
7. Things worked fine......

Now for the problem:
After I reboot the system, module wl doesn't load. Here is some additional info:
a1) lsmod shows the module "ssb" is loaded despite being blacklisted. (b43 isn't loaded)
a2) If I unload ssb ("sudo rmmod ssb"); and load wl ("sudo modprobe wl"); the wireless network comes up.
a3) Strangely, even after this, "lspci -v" shows (note the last line) ssb:

0b:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)
    Subsystem: Dell Device 000b
    Flags: bus master, fast devsel, latency 0, IRQ 17
    Memory at fe7fc000 (64-bit, non-prefetchable) [size=16K]
    Capabilities: <access denied>
    Kernel driver in use: wl
    Kernel modules: wl, ssb

a4) Something else (not sure whether this is a related problem): Quite randomly, my "internet access" packs up after working for an hour or so.. (no, not a DNS entry problem; resolv.conf is fine; default route (route -v) is fine; I can reach IPs in my LAN; Can't reach anthing outside; other machines on the LAN can! Only a reboot fixes it).

Re: Broadcom wireless module doesn't load at boot time

This problem went away by itself ... wierd!
I checked with repeated reboots, and each time now, the wl module loads as intended.
"lspci -v" still shows ssb as a kernel module for the ethernet adapter as in the previous post, but it seems to respect the blacklist.
