Which 64bit Linux distribution for HP625?

[MartinInFrankfurt]

I did try the Suse Linux Enterprise Desktop x86_64, but the x86_64 driver for the Broadcom WiFi module from the i586.repo on the HP site (broadcom-wl-kmp-default-5.100.82.38_k2.6.34.7_0.7-7.pm.9.1.x86_64) requires kernel(default:kernel)=90e8e1919322f8fe which is not supplied by SLED SP1.It is part of the openSuSE11.3 OSS and requires in turn a newer version of mkinitrd.
Once I install the required kernel/mkinitrd from openSuSE 11.3 OSS I still do not get 802.11n as advertised.

I would pay for extra support but from whom?
HP or novell?
Not to mention the ATI and the Bluetooth drivers.
Bluetooth adapter recognition might be an issue of gnome(+) vs.KDE(-), however,by now, with my beautiful hardware with preconfigured Linux and 8Gb RAM at a bargain price, I feel close to the wild goose at the end of the rainbow.
