Indeed. Instead of consolidating, we seem to get more of them: offb, vesafb, efifb, ... cfr. near the tail of drivers/video/Makefile (don't know about all of them): # Platform or fallback drivers go here obj-$(CONFIG_FB_UVESA) += uvesafb.o obj-$(CONFIG_FB_VESA) += vesafb.o obj-$(CONFIG_FB_EFI) += efifb.o obj-$(CONFIG_FB_VGA16) += vga16fb.o obj-$(CONFIG_FB_OF) += offb.o obj-$(CONFIG_FB_BF537_LQ035) += bf537-lq035.o obj-$(CONFIG_FB_BF54X_LQ043) += bf54x-lq043fb.o obj-$(CONFIG_FB_BFIN_LQ035Q1) += bfin-lq035q1-fb.o obj-$(CONFIG_FB_BFIN_T350MCQB) += bfin-t350mcqb-fb.o obj-$(CONFIG_FB_BFIN_7393) += bfin_adv7393fb.o obj-$(CONFIG_FB_MX3) += mx3fb.o obj-$(CONFIG_FB_DA8XX) += da8xx-fb.o obj-$(CONFIG_FB_MXS) += mxsfb.o obj-$(CONFIG_FB_SSD1307) += ssd1307fb.o # the test framebuffer is last obj-$(CONFIG_FB_VIRTUAL) += vfb.o Gr{oetje,eeting}s, Geert -- Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- ge...@linux-m68k.org In personal conversations with technical people, I call myself a hacker.
