I call this the hard and long way ;-)

Original initrd brings more modules:

aic7xxx ata_generic crc-itu-t drm ext2 fat firewire-core firewire-ohci firewire-sbp2 i2c-algo-bit i2c-core i810 i830 i915 mga mmc_block mmc_core mptbase mptsas mptscsih msdos nouveau output pata_acpi pata_ali pata_amd pata_artop pata_atiixp pata_cmd640 pata_cmd64x pata_cs5520 pata_cs5530 pata_cs5535 pata_cs5536 pata_cypress pata_efar pata_hpt366 pata_hpt37x pata_hpt3x2n pata_hpt3x3 pata_it8213 pata_it821x pata_jmicron pata_marvell pata_mpiix pata_netcell pata_ninja32 pata_ns87410 pata_ns87415 pata_oldpiix pata_optidma pata_opti pata_pcmcia pata_pdc2027x pata_pdc202xx_old pata_qdi pata_sch pata_serverworks pata_sil680 pata_sis pata_sl82c105 pata_triflex pata_via r128 radeon sata_inic162x sata_mv sata_nv sata_promise sata_qstor sata_sil24 sata_sil sata_sis sata_svw sata_sx4 sata_uli sata_via sata_vsc savage scsi_transport_sas scsi_transport_spi sdhci sdhci-pci sis squashfs sym53c8xx tdfx udf usb-storage vfat via video

I get the list doing:
$ cp initrd0.img img.gz ; gunzip img.gz
$ mkdir d ; cd d ; cpio -idv  < ../img
$ (for i in `find .  | grep "\.ko$"`; do basename $i | sed 's/.ko//'  ; done ) | sort

here I use mkliveinitrd.

*I believe it should have a easiest way to do it.*
