OK, after a mainboard replacement by HP, I have my AMD64
HP Pavilion DV6000 (DV6615ea) back and a quick update has given me working wireless! The last remaining obstacle has gone - the most recent 2.6.24 kernel update includes working support for the Broadcom Corporation BCM94311MCG wlan mini-PCI (rev 02) in the b43 kernel driver.
a little tip
When connecting this laptop to the mains for a recharge, plug into the mains before connecting the mains lead to the laptop itself. I have a strong suspicion (but it is no more than that) the repair was caused by a power spike from a dodgy extension cable. Plugging into the extension without the other end being connected to the laptop isolates such spikes.
Necessary support

Wireless config
The first dmesg output showed a useful tip:
Apr 4 20:07:06 dwarf kernel: b43-phy0 ERROR:
YOUR FIRMWARE IS TOO NEW. Please downgrade your firmware.
Apr 4 20:07:06 dwarf kernel: b43-phy0 ERROR:
Use this firmware tarball: http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2
Apr 4 20:07:06 dwarf kernel: b43-phy0 ERROR:
Use this b43-fwcutter tarball: http://bu3sch.de/b43/fwcutter/b43-fwcutter-009.tar.bz2
Apr 4 20:07:06 dwarf kernel: b43-phy0 ERROR: Read, understand and _do_ what this message says, please.
Unpack the b43-fwcutter and call
make. Execute
./b43-fwcutter ../broadcom-wl-4.80.53.0/kmod/wl_apsta.o, remove any existing firmware in
/lib/firmware/b43/ and replace it with the content created by b43-fwcutter.
Reboot to load the updated firmware into the kernel and your amber wireless light will flash blue.
sudo iwlist scan then shows the available access points and network-manager is able to connect without problems.
I'm posting this from the HP laptop over wireless.
Summary: this laptop should be eminently supportable in Lenny
After all my doubts and all the hassle, providing you use 'noapic nolapic' and the support of the Debian-Installer for Lenny.
