Official Linux kernel has S3C6410 support since the 2.6.30 version...

[edit] Overclocking

Execute this little script with HaReT to set 667Mhz Speed (From Tanguy Pruvot) 

pfh 0x7e00f000 1 0x1000
pfw 0x7e00f00c 1 0xc14d0301
msgbox overclock "frequency set to 667Mhz" 0
exit

To Restore to 533Mhz 

pfh 0x7e00f000 1 0x1000
pfw 0x7e00f00c 1 0xc10a0301
msgbox overclock "frequency set to 553Mhz" 0
exit
