Ati X300 devid 5460 works in all versions so far with a number of hacks:

10.4.6: use callisto003 fixed for full res and koverg Radeon9700 patch for qe&ci
10.4.7: idem
10.4.8: idem
10.4.9: use callisto003 fixed for full res, use 10.4.8 Radeon9700 kexts + koverg patch for qe&ci or use this kext: http://netkas.freeflux.net/blog/arch...ackintosh.html

All-in-one patch package works from 10.4.6-10.4.8 directly, for 10.4.9 replace the Radeon9700 kexts with the one mentioned above and only after that apply the patch.
