As far as I remember I saw some places in the code which should be fixed before split 1/3 can be used. Split 0.5/3.5 can be not-working if you are using PAE-enabled kernel (in some places pgds are copied directly - i.e. 1GB granularity is used). Anyway due to bug in glibc pthread lib some apps are not working properly with non-standart 3/1 split (i.e. java). I'm working on 4GB/4GB split now (kernel space is separated from user space completely). If someone wants to have a look at it I will probably post it later. Kirill
