I have one Super GC and one GC here. Without modifications, none of them worked out of the box with QL-SD. After a bit of fiddling with added RC filters and pull-downs, I could at least get the SGC to work reliably with QL-SD in one of my QLs. Whether it works or not, is apparently depending on the QL issue as well - Earlier models surprisingly seem to work better, IMHO. Out of 3 QLs, the one that works best is a very early MGG. The others seem to work well for some time with the SGC + QL-SD, but develop intermediate write errors after several hours of running (which can unfortunately destroy the file system image beyond readability, so you want that to work "rock solid").
You shouldn't just assume "it might work" - If it does, you're lucky, but you'd better assume it won't. (This is not blaming the QL-SD itself, rather more the very bad combined signal quality of the QL and the (S)GC, which seemingly push the original QL's design to the limits)

We will try on some Samsung Mad QL (italian) If it can work ^_^
