Damn!! Only for bootsplash i've spent 5 days to configuring my Slack box. It's all because that damned framebuffer device on my intel 815 onboard vga. By default i810 based cards doesn't accept lilo standard command to using non-standard VESA framebuffer console resolution (ie. VESA framebuffer console @ 1024x768x64k or option vga=791). i810 based cards need several argument such as hsync and vsync value to be defined. And for convenient ways to setting up those value, i've built the driver right into the kernel so it won't be usable to be used with another vga card. But that's ok, since i'm not going to change my box to another pc at least in short time hehehehehehe....
I'm using kernel 126.96.36.199, latest stable version until the end of March. For bootsplash patch, i'm using patch from 2.6.15 version (it's still compatible). This is my kernel config:
Device Drivers ->
<*> RAM disk support
[*] Initial RAM disk (initrd) support
