Antonio, Thanks for the good news report on the functionality of slamr under 2.6.20 kernels A very minor clarificaion concerning the "Tainted kernel" message is needed It is first useful to point out that device support is frequently split into two (or more) compiled components. The driver (the slamr.ko in your case) is the component which is most closely coupled with the kernel, and must be compiled anew to match any change in the kernel, . There may be additional non-driver support specific to the device, such as the slmodemd which remain functional across kernel changes. The Tainted warning occurs as any driver with a Closed Source code component is loaded into the kernel, whether it be slamr, Intel537, the ltmodem and several others. It relects the nuisance that one a Closed Source driver has been loaded, subsequent usage of routine debugging tools will generally be flawed. In constrast the following actions of slmodemd helper function through the slamr do NOT evoke a further Tainted message. Correspondingly when any of the Open Source ALSA modem drivers are loaded, there is no Tainted message then, nor during subsequent actions of slmodemd. This is a great blessing of maintainer Sasha's split of the original Smartlink code, so that the Closed Source component is now totally in the non-driver slmodemd. It enables fixes simple debugging/upgrades of the ALSA modem drivers. Alexei Chentsov has accomplished a similar split of the old ltmodem code, so that the old Closed Source ltmdmobj.o component is entirely in the non-driver martian_modem utility, while the martian_dev driver is entirely Open Source.

This is a sucess report that slmodemd works with 2.6.20 or greater kernel. I noticed that some distros run binary modules in kenrl 2.6.20 and I wanted to try if slmodemd worked and it does work. The only thing is that the message thet slmodemd taints kernel, but it still works. This is only a sucess report.
