I'll just weigh in on my experience (i.e. the one @astronautlevel detailed) with my N3DS:
I ended up installing the beta via restoring a good 2.1 backup through Decrypt9 and then using the Gateway site (I restored to 9.2, not 11.0). I dumped the firm0 and firm1 partitions for later analysis since I knew Normmatt and others would be interested in it, and I then went to restore my 11.0 NAND backup that had the "good" A9LH on it (i.e. an open source one). To my horror, the NAND restore tool said "NAND.BIN ERROR", so I tried a few other backups, and those all met the same error. I then dumped the Gateway NAND and tried restoring it immediately, same error. So I tried using my hardmod to restore, and Win32diskimager says the SD is locked, when it isn't (my JST SD adapter has the lock switch glued in place, so it can't possibly be locked). Also, saving things to the NAND when in the 3DS OS works fine, so it's as if Gateway has placed a write lock when NATIVE_FIRM is not running. So currently my N3DS is married to my Gateway card, and I can't do much else with it, unless I possibly try using PlaiSysUpdater to overwrite FIRM, or maybe boot NTRCardHax to run Decrypt9 (which should work, assuming Gateway is using 10.2 FIRM).
TL;DR: Don't install this, it's not a fun situation to be in. At the moment I'm waiting on Normmatt to hopefully pass on some good news.
Edit: I've since escaped my predicament.
